Industrial Wireless Activity Detector
Introducing NCD’s Industrial Wireless Activity Detector, boasting up to a 28 Mile range using a wireless mesh networking architecture. It incorporates a high accuracy acceleration sensor for measuring acceleration changes. Utilizing the interrupt feature of this sensor, it is able to minimize power consumption by making most of the components go to sleep while waiting for the interrupt from the sensor.
User can configure the Activity Detection condition (interrupt settings) using the configuration mode. User can configure acceleration range, data rate, interrupt duration and interrupt threshold. Interrupt duration is dependent upon data rate. It is the duration for which an interrupt condition has to hold to generate a system interrupt and initiate data transmission to a nearby receiver. Interrupt threshold is dependent upon acceleration range and it is the acceleration in g which if exceeded causes interrupt to fire. Note that the absolute value of actual g reading is compared with it therefore it works for both positive and negative acceleration exceeding threshold.
User can also setup interrupt settings. Interrupt settings also user to setup whether an acceleration above or below threshold will fire interrupt. This can be configured separately for all the axis. Moreover, the user can setup OR/AND gates between the interrupts. This allows activity detection (system interrupt) if any single axis interrupt fires (OR condition) or if all axis interrupts fire (AND condition). User can also configure a delay time in seconds which disables the interrupt for that amount of time after a successful interrupt. This enables a user to make sure that the sensor does not drain its battery (with continuous transmissions) if an interrupt condition persists or a wrong condition is accidentally programmed. This time is also used to send a periodic packet to a receiver with latest available data.
Powered by just 4 AA batteries and an operational lifetime of 300,000 wireless transmissions, a 10 year battery life can be expected depending on environmental conditions and the data transmission interval. Optionally, this sensor may be externally powered.
With an open communication protocol, this sensor can be integrated with just about any control system or gateway. Data can be transmitted to a PC, a Raspberry Pi, to Microsoft Azure® IoT, or Arduino. Sensor parameters and wireless transmission settings can be changed on the go using the open communication protocol which provides maximum configurability depending on the intended application.
The long range, price, accuracy, battery life and security features of Wireless Activity Detector makes it an affordable choice which exceeds the requirements for most of the industrial as well as consumer market applications.
NOTE: The current version of this sensor does not support the inbuilt temperature sensor.
Receiving Data From Industrial Wireless Activity Detector
This Industrial Wireless Activity Detector device sends data periodically, based on user-preset timing intervals. Data transmissions include battery level, signal strength, payload, firmware version, sensor type, and device serial number. Please see the Resources section to see detailed information on the data structure of this device. This Industrial Wireless Vibration Temperature Sensor is a wireless transmitter that needs a receiver. There are many options available for receiving data from NCD transmitters. We highly recommend using our USB Modem (available during purchase) so you can monitor this device and use our LabVIEW software for changing device settings. Using our long-range USB wireless modem, users can expect easy operation over a virtual COM port at 115.2K baud. Optionally, we offer a Wireless receiver that operates over Ethernet. Data from NCD sensors will appear over TCP/IP on port 2101. Simply open a TCP/IP socket, port 2101, to the IP address of the Ethernet modem and see your data stream in to your local area network.
Now Supporting Microsoft Azure® IoT
We’ve been working with Microsoft engineers to post data from our sensors to Azure®. If you need help integrating this sensor into Azure®, please let us know and we will work with you to get you connected!

900HP-S3B Industrial Wireless Mesh
Long-Range Wireless Mesh networking is our favorite of all wireless communication technologies. This is the ONLY communications technology NCD recommends on the factory floor, operating at a safe 900MHz. Mesh technology will hop data from one location to another to reach its intended destination, users do not need to do anything other than make sure wireless modules stay within hopping range of each other. We use the Digi 900HP-S3B module in our products, as this is the best the industry has to offer. With a 2 mile range between modules and up to 8 hops, it is possible to cover 16 miles of wireless territory using this technology. Using high-gain antennas, this module is capable of communicating to a remote module up to 28 miles away.
