Long Description

DHT22 Temperature and Humidity Sensor Module The DHT22 Temperature and Humidity Sensor is a basic and economical digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the ambient air and emits a digital signal on the data pin. It's quite simple to use, but requires precise timing to capture data. Simply connect the first pin on the left to a 3 to 5 V power supply, the second pin to the data input pin and the rightmost pin to ground. Although it uses a single wire to send data, it is not compatible with Dallas One Wire! If you want multiple sensors, everyone must have their own data pin! We have written an Arduino library with a sample code Compared to DHT11, this sensor is more accurate, more accurate and works in a wider range of temperature / humidity, but it is bigger and more expensive TECHNICAL DETAILS Power supply 3 to 5 V and I / O Maximum current usage of 5 mA during conversion (when requesting data) Good for 0-100% humidity readings with 2-5% accuracy Good for -40 temperature readings at 80 ° C Accuracy of ± 0.5 ° C No more than 0.5 Hz sampling rate (once every 2 seconds) Body Size 27mm x 59mm x 13.5mm (1.05 "x 2.32" x 0.53 " ) 4-pin, spacing of 0.1 "Weight (just the DHT22): 2.4g
