Feed: ESPHome - DIY CO2 sensor
My favorite sensors is the Co2 sensor!
When the level is too high you can feel tired, your start yawning and it can give you a headache. Also your consentration drops immediately.
With active alerts to open a window you keep healthy and fresh! After I installed them in my home office and living room I’m aware of it now.
I created a cheap one myself. If you want a nice challenge, and want to learn how to create one yourself this is a good project for you as well. You don’t need to solder.
The only steps to take are: connect the sensor to an ESP board and with the ESPHome software flash the code on it.
