DHT11 Digital Temperature & Humidity Sensor Module

The DHT11 Digital Temperature & Humidity Sensor Module is a compact and reliable sensor designed to measure ambient temperature and relative humidity using a single digital output pin. It integrates a calibrated capacitive humidity sensor and an NTC thermistor with an onboard microcontroller to provide stable and accurate environmental data.

Operating from 3.3V to 5V, the module is directly compatible with popular development platforms such as Arduino, ESP32, ESP8266, STM32, Raspberry Pi, and other microcontrollers. Its onboard pull-up resistor, status LED, and mounting holes make installation quick and convenient.

The DHT11 is an excellent choice for educational projects, weather stations, home automation, HVAC monitoring, environmental sensing, smart agriculture, and IoT applications where affordable and reliable temperature and humidity monitoring is required.
