DHT11 Temperature and Humidity Sensor

DHT11 Digital Temperature And Humidity Sensor is a basic and low-cost digital temperature and humidity sensor.

• This sensor is used for projects where accuracy and precision doesn't play big role.
• This comes in a blue perforated plastic enclosure.
• This has four pin.
• There is an upgraded version of the DHT11 temperature and humidity sensor available, which is DHT22 Sensor 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 Celsius 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.
• This sensor is also available as module.
• DHT11 Sensor Specifications: Temperature measurement accuracy: ±2.0 Output Signal Digital Temperature Range 0 to 50º C Humidity Range: 20 to 90% RH Humidity Accuracy: ± 5% RH Power Supply: 3.3 to 5V Size: 2.3cm x 1.2cm x 0.5cm Package Includes: 1 x DHT11 Temperature and Humidity Sensor.
