Module with DHT11 Temperature and Humidity Sensor

Description

Compact module with DHT11 temperature and humidity sensor. Ideal for use with the ESP8266 Wi-Fi module (not included) to build temperature and humidity acquisition nodes for Smart Home or IoT projects. The DHT11 sensor measures temperatures from 0°C to +50°C and relative humidity from 20% to 90%. Power supply from 3.7 V (3.7 V lithium battery) to 12 V.

Warning! The ESP8266 module is not included (see related products).
