Rain Sensor Tutorial for Arduino, ESP8266 and ESP32

2020-04-27· To increase the lifetime of the rain sensor we reduce the operating voltage from 5V to and also only provide voltage to the sensor when we want to read the sensor values with the microcontroller. Therefore we change the wiring and do not longer connect the 5V pin of the Arduino microcontroller or the VIN pin of the ESP8266 and ESP32 based microcontroller to the control board …

GitHub - dr0i/ESP32: my fiddlings with ESP32

Read the MH-Z14A CO2-Sensor. That was hard - I got some plausible, but very round measure (either 410 ppm or 430 ppm) around 12 times (~1 minute) (this is normal, so wait a bit till the sensor sends correct data) after which I got permanently 5000 ppm and sometimes -1 . 5000 ppm happens to be the maximum of the sensors measuring capacity. That's also the value written to output after the ...
