I have several CO2 sensors in use to control the ventilation unit of our house. (Sensirion SCD30 sensor + ESP32).

The micro controller is powered with a standard 5V USB charger. The sensor housing is attached with a clamp to the USB charger. I soldered a USB power cable to make it a bit more compact (the housing still protrudes a bit from the wall)

Extra material:

2x M5x30 countersunk bolt ISO10642

2x hex nut M5

USB charger (I used 20W dual USB port plugs from ‘Schitec’ available at Amazon)
