DHT11 is a popular temperature and humidity based digital sensor. There is an upgraded version of the DHT11 temperature and humidity sensor available, which is DHT22 Sesnor with higher sensing ranges.

The sensor uses a capacitive humidity sensor and a thermistor based temperature sensor to measure the ambient humidity and temperature. The humidity sensing ranges from 20% to 90% with ±5% accuracy and the temperature sensing ranges from 0 degrees to the 50 degrees Celcius with ±2°C accuracy. The sampling time of this sensor is 2 seconds almost. This Temperature and Humidity Sensor uses digital pins to communicate with the microcontroller unit and does not have any kind of analog pins.

The module also has the inbuilt pull-up resistor and additional filter capacitor to support the DHT11 sensor. Thus the module is available in ready to go mode and can be directly connected with the microcontroller unit without using any kind of additional components.

 

Pin Description:-

  • Pin 1: Power VCC(+) (3.3VDC to 5.5VDC )
  • Pin 2: Digital Serial Data Output
  • Pin 3: Ground
DHT11 Sesnor Pinout

The above image is showing the pinout of the DHT11 sensor. Connect 3.3-5.5V in the VCC (+) pin and ground on the GND(-) pin. Connect the middle pin which is a digital output of the sensor module with a microcontroller digital I/O pin. Use the referenced library that is given below of this page for interfacing the sensor with the microcontroller unit.
