Device Overview
NCD’s Long Range Industrial IoT Wireless CO2 Temperature Humidity Sensor offers air quality monitoring with an integrated temperature and humidity sensor, featuring up to a 2-mile range using wireless mesh networking. It transmits accurate CO2 concentration, temperature, and humidity data at user-defined intervals. CMOSens® technology provides precise CO2 measurements, while NDIR technology and a high-quality humidity and temperature sensor enhance accuracy.
The sensor compensates for long-term drifts using a dual-channel design, and its compact size allows easy integration. It operates from -25°C to 85°C and 0-90% RH, powered by 6 AA batteries with up to 5 years of life, depending on use. Its range, accuracy, and battery life make it a cost-effective solution for industrial and consumer applications.

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.
