Description

Medium Precision Temperature and Humidity Sensor DHT22 (better than DHT11) with 1-Wire Data Bus, for microcontroller like Arduino, Raspberry, and others. Aosong AM2302 is a calibrated, integrated humidity and temperature sensor, communicating to a microcontroller over only 1 digital I/O pin. The sensor provides 16bit resolution, takes only about 0.3mA (0.06mA in standby), and needs a power supply in the range of 3.5 to 5.5V. The sensor is very easy to connect, and a library and example code for Arduino is available. The DHT22 is a more precisely device than the cheaper DHT11. You find a comparison in the following list: 3 to 5V power and I/O 2.5mA max current use during conversion (while requesting data) Good for 0-100% humidity readings with 2-5% accuracy (DHT11: 20-80% with 5%) Good for -40 to 80C temperature readings +/- 0.5C accuracy (DHT11: 0-50C with 2%) No more than 0.5 Hz sampling rate (DHT11: 1 Hz) Body size 15.1mm x 25mm x 7.7mm 4 pins with 0.1″ spacing
