SG112A - Air Quality monitoring with CO2 sensor module - Nanotron

September 13, 2021

The nanotron / Inpixon CO2 Dual Channel NDIR Gas Sensor Module, helps monitor air quality within commercial buildings for critical visibility to ensure a safer, more productive indoor environment.
With the SG112A, CO2 sensor module, is it possible to measure air quality with a high accuracy (up to 5000 ppm) by using advanced non-dispersive infrared technology, that is very suitable in IoT applications. With a serial or PWM interface the data is easily configurable for alarms and thresholds. The small size (30x15.3x7.7mm) and the 2.7gram of weight it is used in building automation like HVAC and other indoor applications.


Monitor Indoor Air Quality for CO2 Concentrations up to 5,000 ppm

The Inpixon SG112A CO2 sensor module is a compact IoT sensor module that uses advanced non-dispersive infrared technology to deliver high accuracy monitoring of ambient air quality within commercial buildings. It delivers long-term stability, a wide range of gas readings, and configurable concentration alarm indication levels for situational awareness that helps accurately identify harmful fluctuations. With an autonomous self-calibration function, the sensor offers dependable performance by eliminating sensor signal drifts caused by environmental changes and component ageing. Among the smallest of its kind, the low power sensor features multiple digital interfaces, supporting seamless integration with other hardware systems. This sensor can be integrated into building automation or HVAC systems to reliably measure CO2 concentration, ensuring a clean and safe indoor air supply.
