Overview

This module is based on DHT11, a high performance temperature and humidity sensor, ensuring high reliability and excellent stability.

The temperature is measured using a negative temperature coefficient thermistor (NTC), and the relative humidity is measured using a capacitive sensor. Those sensing elements are pre-calibrated and the output is provided as a digital signal.

The DHT11 sensor is compatible with most of the popular microcontroller development boards, like Arduino.
