Great addition to my Apollo msr-2 so that I can read the c02 levels at home. Easy to install as long as you line up the x on the sensor with the x on the board. I plugged the complete setup to a battery. Took it outside for a little over 5 min and hit calibrate in home assistant. Brought it back inside and got readings quickly.
