How Does a TVOC Sensor Actually Work?

MOS (metal oxide semi-conductors) work by heating a thin film, or surface, of metal-oxide particles. In Kaiterra products, this is a thin film of metal-oxide nanoparticles. This film is heated to around 300’C (hence the warm up period after turning on a Kaiterra device). During operation, oxygen particles will be adsorbed on the surface, and ...

CO2 Sensor Calibration: What You Need to Know |

All carbon dioxide sensors need calibration. Depending on the application, this can be accomplished by calibrating the sensor to a known gas or using the automatic baseline calibration (ABC) method. Both have pros and cons you should know. Most of our CO2 products use non-dispersive infrared (NDIR) carbon dioxide sensors.

Wireless CO2 Sensor Reference Guide

The sensor has a one-point calibration in the software with a default value of 400 ppm (user editable). If you have a meter that provides an accurate carbon dioxide measurement, you may want to edit the default value. A two-point calibration is not possible. The user can reset to the factory calibration which is stored in the probe at any time.

CO2_Sensor_SKU_SEN0159-DFRobot

This is the first CO2 sensor on the opensource hardware market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. Once the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released.
