ESP8266 Wi-Fi Module + DHT11 Temperature and Humidity Sensor

Description

Compact module with ESP8266 Wi-Fi and DHT11 temperature and humidity sensor. Ideal for building 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%. The ESP8266 is a small Wi-Fi transceiver module, compatible with the 802.11 b/g/n standard at 2.4 GHz, featuring a serial interface and PCB antenna. Power supply from 3.7 V (3.7 V lithium battery) to 12 V.
