This Keyes-015 Temperature & Humidity Sensor is based on the DHT111 and has a temperature & humidity sensor complex with a calibrated digital signal output.

By using a digital-signal-acquisition technique and temperature & humidity sensing technology, it can ensure high reliability long-term stability. This sensor has a resistive-type humidity measurement component and an NTC temperature measurement part and connects to a 8-bit microcontroller, offering fast response noise immunity.
