ESP32 Arduino: Temperature, humidity and CO2 concentration ...

+

05/05/2018· Hi! None of the sensors use I2C. The CO2 sensor is analog and the Temperature / Humidity sensor uses the single wire protocol. Regarding the one wire bus and the DHT22, I don’t recall what is the actual library behavior if we try to do multiple requests without respecting the minimum time interval between measurements.
