Device Overview
Introducing NCD’s Long Range Industrial IoT Wireless CO2, Temperature, Humidity, and Particulate Matter Sensor for air quality monitoring. It features a range of up to 2 miles using wireless mesh networking, transmitting CO2 concentration, particulate size, mass, temperature, and humidity data at customizable intervals.
The sensor uses CMOSens® Technology for precise CO2 measurement, along with NDIR technology for CO2 detection. It includes a best-in-class humidity and temperature sensor, which compensates for external heat sources without additional components. The dual-channel design ensures long-term stability in CO2 measurement.
The particulate matter sensor measures PM1.0, PM2.5, PM4.0, and PM10.0 particles, which can cause serious health issues like asthma and cardiovascular disease. It uses laser scattering technology for precise measurements and includes a fan for automatic sensor cleaning every 10 transmissions.
The temperature sensor operates from -25°C to 85°C (-13°F to 185°F), while the humidity sensor handles 0-100% RH. Powered by 6 AA batteries, the sensor offers up to 3 years of battery life, with external power options available on request.

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.
