Sensor Data Overview

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).

Good to know...

NCD wireless sensors transmit data and require a receiver.  There are many options available for receiving data from NCD IoT devices, which will be discussed in much greater detail here. We highly recommend at least one USB Modem for the purposes of sensor configuration (available during checkout). Also, our LabVIEW software is typically used for advanced sensor configuration, which is located in the "Resources" tab above.

How long Will the Batteries really Last?

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 a standard alkaline, 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.

The Truth About Battery Life

Under the best of circumstances, the best non-rechargeable batteries commonly available today are limited to a 25 year non-working shelf life in a room temperature environment. Factors such as actual usage, temperature, and humidity will impact the actual working life. Also note that most battery chemistries are not rated for use in extreme temperatures. NCD only uses the best Non-Rechargeable Lithium batteries available today, which are also rated for use in extreme temperatures and have been tested by our customers in light radioactive environments. Actual battery life will be determined by many factors, but we suggest the use of Lithium batteries for best possible energy density and extreme temperature battery life. The ratings provided here are for Energizer® Ultimate Lithium Batteries. Alkaline and other battery chemistries will not achieve the ratings shown on this page.

How Do I Change Settings and Examine Raw Sensor Data?

Using our long-range USB wireless modem, users can expect easy operation over a virtual COM port at 115.2K baud.  Simply open the virtual COM port of the USB modem and watch data stream in.  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.  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.
