Our long range wireless enterprise series sensors are an easy to use and reliable start to any data aggregation application. This video will demonstrate how they work, what they do, and how to use them.
Introducing NCD’s Long Range One Channel IoT Wireless 4-20mA Current Receiver, boasting up to a 2 Mile range using a wireless mesh networking architecture. It incorporates a 1 channel 10-bit ADC that samples 4-20mA analog inputs at user defined intervals and transmits the result to remote modems and gateways. Between samples, this device enters a ultra-low power sleep mode to minimize power consumption. This IoT Wireless 4-20mA Current Receiver has an additional feature of detecting change in voltage every 7 seconds (user configurable) and sending out ADC samples if the change in voltage on any channel is greater than 10% (user configurable). Both features work simultaneously to support multiple application areas in one package.
Powered by just 2 AA batteries and an operational lifetime of 500,000 wireless transmissions, a 10 years battery life can be expected depending on environmental conditions and the data transmission interval. Optionally, this sensor may be externally powered.
We take IoT security very seriously, which is why we encrypt every IoT sensor, gateway, modem, and device in the NCD Enterprise product line. Encryption is much easier to manage than you might expect, as the encryption does not get in the way of using the device. We include a standard 128-Bit AES Encryption key with every device or we can help you integrate a new encryption key into all of your devices. All hardware devices must use the same encryption key. Once the keys are set, the hardware manages the rest for you, 100% in the background.
NCD long-range wireless IoT sensors use the DigiMesh® protocol from Digi.com. DigiMesh® was designed by THE industrial leader in secure wireless communications for industrial applications. DigiMesh® automatically hops data from gateway to gateway until it arrives at the desired destination. NCD IoT sensors are capable of a 2-Mile line-of-site communication distance with the included antennas and up to 28-mile range when using high-gain antennas.
Your data belongs to YOU and it’s up to you to decide where you want your IoT sensor data to arrive. Don’t be bogged down by the limitations of proprietary cloud solutions, post the data where you need it most. We offer an open communications protocol so you can integrate NCD wireless transmitters into your own software. This allows integration of NCD IoT sensors into any control system or gateway you could ever imagine. Send data to a PC, Mac, or Linux computer, or a Raspberry Pi using NCD modems. Send data to popular cloud platforms such as Microsoft® Azure® IoT, Losant, and MQTT using NCD Micro Gateways. We can also help get data from NCD wireless IoT sensors to embedded platforms such as Arduino. We also offer sample code for Microsoft® Visual Studio, Node-RED, LabVIEW®, and Python. Our documentation fully breaks down the packet structure, so integration into other languages is possible. We may even be able to help, so please feel free to contact us if you are working with a platform not mentioned here.
The long range, price, accuracy, battery life and security features of Long Range IoT Wireless Analog to Digital Converter makes it an affordable choice which exceeds the requirements for most of the industrial as well as consumer market applications.
NOTE: This 4-20mA Current Receiver Does Not Provide Current Loop Power Supply.
This formula can be used to convert a raw Analog Value into 4-20mA.
mA = raw_adc * 0.020
This device sends data periodically, based on user-preset timing intervals.
This device sends data when a preset percentage of change is detected on the input.
NCD IoT Sensors send a lot more than just sensor data. For instance, a unique serial number is sent so you can always identify a particular sensor on the network. A Node ID is also included, which a single byte of data that you can use for anything, such as the floor of a building or to help identify which group a sensor belongs to. Also included in the data packet is a firmware version, battery level, and sensor type. This allows your software to positively identify and manage the health of NCD IoT wireless sensors. While signal strength data is also available, it is handled in a different way, and is not included in the sensor data packet (but rest assured, signal strength data for each sensor is available). Please see the Resources tab to see detailed information on the data structure of this device.
Most NCD IoT Sensors are rated for 300,000 to 500,000 transmissions until the batteries become so weak they are unreliable. You could spread these transmissions out over a 10 year period and send 50,000 transmissions per year. This would allow up to 136 transmissions per day, or about 5 transmissions per hour (for a 500K sensor, or 3 per hour for 300K sensor). If you only need the batteries to last 3 years, you could send 166,666 transmissions per year, or about 456 transmissions per day (about 19 transmissions per hour for a 500K sensor). As you can see, battery life is really up to you. By altering advanced settings in the NCD IoT sensor, you have control over longevity. Please note the 500,000 transmission rating is for premium alkaline batteries. NCD ships all sensors with premium Lithium batteries, which include a ultra-wide temperature range that typically lasts in excess of 600,000 transmissions for some sensor types. These batteries weigh less than half of alkalines, and they work in the freezer! A word of caution though, putting a sensor in configuration mode will drain the batteries very quickly. It’s important to configure your sensors and exit configuration mode as soon as possible or use a external power supply during configuration (if supported by the sensor). The table below indicates how many Transmissions Per Hour (TPH) your can expect from different sensors over a lifespan of up to 10 years.
|Battery Life:||3 Months||6 Months||1 Year||2 Years||3 Years||5 Years||10 Years|
|300K Sensor||136 TPH||68 TPH||34 TPH||17 TPH||11 TPH||6 TPH||3 TPH|
|400K Sensor||180 TPH||90 TPH||45 TPH||22 TPH||15 TPH||9 TPH||4 TPH|
|500K Sensor||228 TPH||114 TPH||57 TPH||28 TPH||19 TPH||11 TPH||5 TPH|
|600K Sensor||272 TPH||136 TPH||68 TPH||34 TPH||22 TPH||13 TPH||6 TPH|
TPH = Transmissions per Hour

We have developed LabVIEW® software for each sensor to change advance sensor settings using both Ethernet and USB modems. Alpha Station also allows display of sensor readings as well as limited configuration (this feature is still in development). Of course gateways are also available for sending data to popular cloud platforms such as Amazon® AWS® IoT, Microsoft® Azure® IoT, and Losant (more information below). We take software samples seriously, so be sure to to check out the “Resources” tab to see code samples for Raspberry Pi, Visual Studio, LabVIEW®, Arduino, Python, and more.
During purchase, you will see three frequency options. Not all options are legal for use in all areas, so it’s important to make the right selection during purchase. We will build your product and accessories based on the options chosen. Here, we will explain these options in much greater detail, but please check your local laws BEFORE purchase.
If you are located in North America, the 900MHz Option will provide the longest range currently supported with the best penetration through walls, buildings, industrial equipment, and trees. This option is also the best choice for long range applications. The official Line of Sight rating for this option is 2 Miles with included antennas or 28 Miles with high-gain antennas. We suggest contacting Digi.com for a high-gain antenna recommendation if required. Please check your local laws before choosing this option.
If you are located in Europe, the 868MHz Option is the longest range choice available at this time. This option offers better penetration through walls, buildings, trees, and industrial equipment than 2.4GHz. The official line of site rating for this option is 14.5km using 2.1dBi antennas. Please check your local laws before choosing this option.
The 2.4GHz option should be chosen if 900MHz and 868MHz are not legal for use in your country. This option is now certified for use worldwide, including Europe, United States, Japan, Australia, Brazil, and South Korea. Please check your local laws before choosing this option just in case 2.4GHz is not legal in your area.
If you are unsure of which sensor option to choose, please contact us. We may be able to help determine which sensors are legal for use in your area.
NCD IoT Sensor Data can be sent anywhere with NO FEES OR HIDDEN COSTS, NOT NOW, NOT EVER! NCD IoT Sensors always provide an open protocol, so you are not tied to any cloud platform. You own your data, so you can do whatever you want with it, no subscriptions, no service contracts, and you can integrate NCD sensors into any software, embedded system, or cloud platform of your own free choice.
Whether you need IoT sensor data on a desktop computer, an IoT cloud platform, or an embedded platform, we have you covered. NCD IoT sensors broadcast data, so data handling is very easy, expandable, and versatile. Send IoT sensor data to Gateways when you want to talk directly to IoT cloud platforms. Send IoT Sensor data to Modems when you want to talk to local computers. Of course you can always send data to both gateways and modems simultaneously, so you always have access to your sensor data locally and remotely. Use multiple Gateways when you need data redundancy or if you need to send sensor data to multiple IoT cloud platforms.
IoT Sensor Clusters are also possible. You can build a cluster of IoT sensors on every floor of a high-rise building, sending data to gateways and modems on each floor. Clustering makes it possible to keep your IoT sensor data separated for easier management. Each Gateway and Modem can be configured to listen to a different cluster of IoT sensors. Because NCD devices support thousands of clusters, expanding your IoT sensor network is virtually limitless.

Pre-loaded with Node-RED and NCD Wireless Sensor Libraries help you get your sensor data connected to a cellular network or connect to Wi-Fi and Ethernet with unprecedented flexibility. This is a perfect solution for developers who are experienced with Node-RED and need the hardware to help get NCD sensors connected for complex integration tasks. Requires experience with Node-RED.
Modems are ideal for communicating to localized computers, servers, and embedded systems. The main purpose of a modem is to convert data from Wireless Sensors and endNode controllers into standard hardware communication formats such as USB Virtual COM Port, Bluetooth Virtual COM Port, Wi-Fi TCP, Ethernet TCP, RS-232, and RS-485. Multiple modems may be used simultaneously, so you are not limited to making a single choice. Add more modems as needed to cover larger areas or explore other communication technologies. Both Modems and Gateways offer long range wireless communications up to 2-Miles line-of-sight. Modems and Gateways may also be used in a Wireless Mesh network to “Hop” data across the wireless network to cover longer distances. Both Modems and Gateways may be grouped into separate networks on each floor of a high-rise building without interference between floors.
We Developed Alpha Station using Visual Studio to demonstrate how IoT sensor data can be received and converted to real-world values. Alpha Station allows you to view and set basic configuration settings of remote sensors up to 2 miles away. Alpha Station supports our Wireless USB Modem, our Mega Modem, and our Wireless Ethernet Modem. The source code and run-time application is available for download on our web site at https://ncd.io/alpha.
We Developed a complete set of Drivers for Node-RED, so you can build your own flows and dashboards to help get you connected. Send NCD IoT sensor data to Node-RED and use flows to build logic operations to send alerts or turn things on or off. Combining Node-RED with NCD IoT sensors gives you limitless power to monitor, control, and visualize data locally and remotely.
The Node-RED Flow Builder is powerful, allowing you to build complex graphs and dashboards in minutes. Node-RED may also be used for advanced Gateway applications. Send data to your favorite IoT Cloud service such as MQTT, Losant, Microsoft® Azure®, or AWS®. Since Node-RED runs on a local computer, a USB, RS-232, Ethernet or Mega Modem is required.
NCD Node-RED Libraries are always expanding, you can read about how to integrate our sensor into Node-RED Here.
We Developed a complete set of tutorials for working with NCD IoT Sensors using LabVIEW®. Use LabVIEW® to configure advanced sensor settings or to graph incoming sensor data. Monitor the battery level of remote sensors and watch sensor data flow over time. We will be adding source code for LabVIEW® in the future, but for now, please contact us if you have a urgent need for source code. Since LabVIEW® runs on a local computer, a USB, RS-232, Ethernet or Mega Modem is required.
Using our LabView software, data logging from a single sensor is also possible. Simply run the software and watch the graph fill with data over time. Export the data into comma delimited tables for use in Excel or into other data analysis tools. Logging data from multiple sensors simultaneously is not supported at this time in our software, but can be accomplished using Losant or Azure web services.
