My experiences with the MH-Z19 NDIR CO2 sensor Warning: I just destroyed my MH-Z19 sensor when soldering, I was changing connectors with lead free solder, iron set to 380 C. I had to heat for a little while to remove the old header. Now the sensor only gives a very low value, both on PWM and serial output. Before destroying the device, I was getting strange values around 900 ppm when I should ...

RPI Node-Red: MH-Z19 CO2 Sensor • T³ Alliance

23/12/2019· The MH-Z19 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) Ground (Black Wire) –> 6 (GND) Tx (Blue Wire) –> 8 (#14 TXD ...
