MH Z19b - Running CO2 sensor on batteries | MySensors Forum

2018-09-10· I'm trying to run the MH Z19b CO2 sensors interfaced by a PIC microcontroller, powered by batteries. I would like to get the most out of the battery life. So, I have used a transistor and a GPIO pin from PIC to control the power supply to the CO2 sensor programmatically. Please find below, the pseudo code of the programming logic I had used to take CO2 measurements from the MH Z19b …

Experiences with an MH-Z19 CO2 sensor | Erland Lewin ...

I am having similar issues using MH Z19B via PWM. Over long time run it shows normal CO2 ppm and sometimes bounces to double value of ppm ( compared with Testo CO2 meter ) with no changes in program nor restart of the system. I also suspect the sensor to change range with no reason and was also to check pwm ratio measurement procedure ( which is the typical one found on internet but using ...
