Device Overview
The NCD Industrial IoT Wireless RTD (Resistance Temperature Detector) Temperature Sensor is capable of measuring extreme high and low temperatures with incredible precision. This IoT RTD Temperature Sensor transmitter supports any 100 Ohm 3-Wire RTD sensor, and includes a free RTD PT100 probe for the purposes of experimentation and testing within room temperature environments, but best results are achieved when connecting a high-quality sensor that meets your application requirements. This Temperature Sensor transmitter includes a on-board RTD signal amplifier for precision measurement. This wireless IoT RTD Temperature Sensor Transmitter is ideal for industrial temperature monitoring applications supporting extreme temperature ranges, such as industrial boiler temperature measurement, liquid temperature measurement, and temperature monitoring of food storage units. The Industrial IoT Wireless RTD Temperature Sensor is designed to consume extremely low power and send data at extremely long distances of up to 2 miles line-of-light or up to 28 miles using high gain antennas.

Status LED
The Status LED is used to indicate errors or other sensor diagnostics.
LED blinks once – Message was sent successfully and no error in last sensor read as well in data transmission.
LED blinks twice and then one more time – Message was sent successfully but there was an error in last sensor read.
LED blinks thrice – MCU is having issue communicating with the radio module.
