Introducing NCD’s Long Range IoT Temperature and Humidity Sensor. Accuracy and power consumption were our primary focuses when developing this sensor. Boasting up to a 28 Mile range, and a wireless mesh networking architecture, this sensor transmits humidity (±1.7%) and temperature (±0.3°C) data at user-defined intervals, sleeping in between to maximize battery life.

Powered by just 2 AA batteries and an operational lifetime of 500,000 wireless transmissions, a 10 year battery life can be achieved with proper calibration.  Optionally, this sensor may be externally powered.

An open communication protocol allows easy integration with just about any control system or gateway.  Data can be transmitted to a PC, Raspberry Pi, or even an Arduino, and sent on to Microsoft Azure®, AWS or Google Cloud Platform. Wireless transmission settings can be changed using the open communication protocol providing maximum configurability depending on the intended application.

The long range, price, accuracy, battery life and security features of our Wireless Temperature and Humidity Sensor make it an ideal choice to start, or expand, your own wireless sensor network using a device which exceeds the requirements for most of the industrial as well as consumer market applications.
