DHT 11 Temperature And Humidity Sensor Module

The DHT 11 Temperature And Humidity Sensor module puts the DHT11 sensor on a small board with header pins, so you can read air temperature and relative humidity from a single digital pin. It is a low-cost, beginner-friendly sensor for Arduino, ESP32 and Raspberry Pi projects such as room monitors, weather stations and greenhouse controllers.

DHT 11 Temperature And Humidity Sensor Specifications

• Resolution: 1 % RH and 1 °C
• Supply voltage: 3.3 V to 5 V
• Interface: single-wire digital signal
• Reading rate: one reading per second at most
• Pins: VCC, DATA (signal) and GND

DHT 11 Temperature And Humidity Sensor Applications

• Indoor climate and room comfort monitors
• Simple weather stations and data loggers
• Greenhouse, incubator and storage room control
• IoT projects that post readings from an ESP32 or ESP8266
• STEM lessons on sensors and data

What's in the Box

• 1 × DHT11 temperature and humidity sensor module

Tip: Use the DHT sensor library in the Arduino IDE and wait at least 1 second between readings. The pin order differs between module makers, so follow the labels printed on the board when wiring VCC, DATA and GND.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
