This digital NDIR CO2 concentration sensor supports MODBUS RS485 serial communications, SDI-12 communication protocols, and is compatible with the wide power supply voltage of 5-16V. It has a built-in calibration functionality and can be widely applied in both indoor and outdoor environments.
Product Description. Overview. Unlike the chemical CO2 sensor(MG811), this NDIR CO2 sensor does not need a constant ON heating element. The heating element inside a chemical CO2 sensor keeps the sensor warm so that the chemical reaction could happen and produce an continuous EMF as the output, which depends on the CO2 concentration.
Breaking the Size Barrier in CO 2 Sensing. The SCD4x series is Sensirion’s next-generation miniature CO 2 sensor that offers the smallest size combined with an unmatched price-to-performance ratio. The series consists of the SCD40 and SCD41 CO 2 sensors. Both sensors are built on the photoacoustic sensing principle and Sensirion’s patented PASens ® and CMOSens ® Technology to enable ...
NDIR is an industry term for "nondispersive infrared", and is the most common type of sensor used to measure carbon dioxide, or infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector.
ExplorIR®-W 5% CO2 Sensor. The ExplorIR®-W is a low power, high performance CO2 sensor that can measure up to 5% CO2 levels. It is suitable for measuring high concentrations of CO2 in closed-loop sampling applications or battery operation in portable sampling instruments. Formerly called the COZIR-WR, this sensor is based on infrared LED ...
Nov 08, 2019· The sensor is a dual channel NDIR CO2 sensor module with 400-5000PPM range (10,000 PPM optional). The sensor can communicate with a host device via UART. The chart below demonstrates the SG112A sensor under test compared to a reference CO2 sensor. This test shows the SG112A tracks very well with the reference sensor.

The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means it's a lot bigger and more expensive, but it is the real thing.
