# Overview

DHT22 is a high performance temperature and humidity sensor, ensuring high reliability and excellent stability.

It uses a capacitive humidity sensor to measure the relative humidity and a negative temperature coefficient thermistor (NTC) to measure the temperature. Those sensing elements are pre-calibrated and the output is provided as a digital signal. Data can be read once every 2 seconds.
