DHT11 temperature and humidity sensor with wires, module for Arduino

DHT11 temperature and humidity sensor module for ESP8266, ESP32, Arduino, Raspberry Pi

The DHT11 temperature and humidity sensor module is based on a single-wire digital interface. It provides temperature measurement in the range of 0 to 50 °C with an accuracy of ± 1 °C, and humidity from 20 to 90% RH with an accuracy of ± 4 RH (at 25 °C).

A low average current consumption of 0.2 mA and supply voltage from 3.3V to 5V make it suitable for energy-efficient projects. Resolution for both temperature and humidity measurements is 8 bits.

The module’s compact size, 14 mm x 20 mm, allows easy integration in various projects. The kit includes three wires for easy connection to the control board.
