Most relative humidity sensors are resistive or capacitive sensors. It’s a fact that the resistance and capacitance of a vast majority of such sensors also depend on the surrounding temperature and a ...

A linear, simple, and reliable capacitive temperature sensor is fabricated with inexpensive materials. The sensor is a parallel plate capacitor, in which the dielectric material polydimethylsiloxne ...

However comparisons are quite fast. uint16_t getRawHumidity () returns the raw two-byte representation of humidity directly from the sensor. uint16_t getRawTemperature () returns the raw two-byte ...

The DHT11, 21, 22, 33 and 44 are relative inexpensive sensors for measuring temperature and humidity. This library can be used for reading both values from these DHT sensors.
