Description

The DHT11 Humidity & Temperature Sensor Module is a basic, low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and outputs a digital signal on the data pin (no analog input pins needed). Its very simple to use, and libraries and sample codes are available for Arduino and Raspberry Pi. RoboticsBD

This DHT11 Humidity & Temperature Sensor Module makes is easy to connect to an Arduino or microcontroller as it includes the pull-up resistor required to use the sensor. Only three connections are required to be made to use the sensor – VCC, GND, and Output. We have also included the cables required to connect the DHT11 to a microcontroller.  Featured By RoboticsBD.

Application:

  1. Indoor Climate Monitoring: Monitor the temperature and humidity levels in homes, offices or greenhouses to ensure optimal living conditions.

  2. Agriculture: Monitor soil moisture levels and environmental conditions to optimize crop growth and yield.

  3. Weather Station: Build a weather station that measures temperature, relative humidity, and pressure to predict weather patterns.

  4. HVAC Control: Automatically control heating, ventilation, and air conditioning systems based on real-time temperature and humidity data.

  5. Humidor Control: Monitor and maintain proper humidity levels for storing cigars, wine or other items sensitive to temperature and humidity fluctuations.
