· GitHub is where people build software. More than 65 million people use GitHub to discover, fork, and contribute to over 200 million projects.
automatic_baseline_calibration (Optional, boolean): MH-Z19 has automatic calibration procedure. The automatic calibration cycle is every 24 hours after powered on. Set this value to false to disable ABC on boot (it’s better if you use sensor indoor). Set this value to true to enable ABC on boot. Doesn’t send calibration command if not set (default sensor logic will be used).

· The MH-Z19 features a UART serial interface and 5V power supply and IO levels. This makes is easy to connect it directly to a Raspberry Pi or to a PC (If PC, you need to use an USB/serial converter(CMOS/TTL levels, not RS232 levels)). It also features an pulse width modulated (PWM) output where the duty cycle changes with CO
MH-Z19 CO2 Sensor. The MH-Z19 is a small non-dispersive 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 increase ...
