Dht22 humidity and temperature sensor
WebDHT22 Temperature & Humidity Sensor. ¶ The DHT22 and DHT11 require external pull up resistors on the data line. To do this, solder a resistor with about 4.7kΩ (anything in the range from 1kΩ to 10kΩ probably works fine, but if you’re having issues try the 4.7kΩ recommended by the manufacturer) between DATA and 3.3V . Web5.1. Description. The DHT22 is a low-cost digital temperature and humidity sensor with a single wire digital interface. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air and spits out a digital signal on the data pin (no analog input pins needed). The sensor is calibrated and doesn’t require extra components ...
