RPI NodeRed: MHZ19 CO2 Sensor • T³ Alliance

20191223· 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) Ground (Black Wire) –> 6 (GND) Tx (Blue Wire) –> 8 (14 TXD ...
