![]() ![]() DHT11 fritzing circuit DHT11 Arduino Code The DHT11 data pin is connected to the arduino digital pin 2. The figure below shows the DHT11 sensor interfacing with arduino. ![]() The parts required for this tutorial are: DHT11 and DHT22 Pin ConfigurationĭHT11 and DHT22 have only three connections: Vcc, GND, and Data. ![]() Connect Pin 1 directly to Supply (3.3V or 5V), pin 4 to GND, and Pin 2 to the microcontroller pin with pull-up resistor to the supply voltage. The circuit diagram below shows DHT sensor Arduino circuit. In summary, the DHT22 a little more accurate have a slightly larger temperature and humidity range.ĭHT11 and DHT22 Specifications DHT11 Sensor ApplicationĭHT11 is usually used in Weather Stations, HVAC, Dehumidifier, data loggers, humidity regulators, Home Appliances, and Consumer Electronics. RangeĠ☌ to 50☌ (Temperature) 20% to 80% (Humidity)ĭHT11 Specifications DHT11 vs DHT22 Specificationsīoth DHT11 and DHT22 have the same pin configuration but have different characteristics. An integrated ADC converter converts the measured values into a digital signal, which is then output via the OneWire interface. It integrates a thermistor and a capacitive humidity sensor. The DHT11 temperature sensor range: 0 – 50☌ (☒☌) and DHT11 humidity sensor range: 20-80% (±5%). The DHT11 sensor is low-cost Temperature and Humidity sensor that is ideal for hobbyists and prototyping applications. ![]()
