MH-Z16 NDIR CO2 Sensor with I2C/UART Interface Board ...

21/09/2015· 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. This NDIR measures the concentration of the CO2 by measure the received …

Indoor air quality sensor | Unipi

For models featuring a CO2 sensor, the LED indicates carbon dioxide concentration (green = low concentration, red = high concentration). For variants lacking the CO2 functionality, the LED then indicates air quality index roughly equivalent to CO2 concentration. In all models, the LED has a secondary function of indicating wireless communication and device status. Users can also adjust the …

Build your own CO2 measuring device easily and ...

The CO2 sensor also has an analogue output, but we don’t use it because the measuring accuracy is lower here. We now connect the pins of the sensors to the pins on the ESP32 with circuit wire according to the wiring diagram and then check again that the wiring is in accordance with the wiring diagram to avoid any trouble later. Now we put our assembled circuit board into the housing and fix ...

Gira KNX/EIB CO2 sensor

The CO2 sensor measures the carbon dioxide concentration in the air in the spectrum from 0 to 2,000 ppm. Independent of the four freely definable limit values, various functions can be controlled via the KNX/EIB system. The limit values of the various sensors can be connected via internal logic gates. Measurement values can be processed further as desired, for example via the Gira HomeServer 3 ...
