RPI NodeRed: MHZ19 CO2 Sensor • T³ Alliance

Dec 23, 2019· The MHZ19 is an Infrared CO2 sensor that talks to the raspberry pi over a serial port. It works by shooting an infrared beam through a sample of some air and measuring the specific frequency of light that CO2 absorbs, then it can calculate the Parts per million CO2 content. Getting Started: Wiring: Power (Red Wire) –> 2 (5v)

MHZ19 CO2 Sensor Home Assistant

MHZ19 CO2 Sensor. The MHZ19 is a small nondispersive infrared sensor that can measure CO2 level. High CO2 levels can lead to drowsiness, poor concentration, loss of attention or increased heart rate. The CO2 level outside is around 400ppm, but inside levels can reach between 1000 and 5000 ppm. High CO2 levels indicate that you should ...
