DHT22 Temperature and Humidity Sensor Module
\nDHT22 (AM2302) \u2013 Humidity and Temperature Sensor is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn\u2019t require extra components so you can get right to measuring relative humidity and temperature.<\/p>\n
Features:
\n3.3-5V Input
\n1-1.5mA measuring current
\n40-50 uA standby current
\nHumidity from 0-100% RH
\n-20 \u2013 80 degrees C temperature range
\n+-2% RH accuracy
\n+-0.5 degrees C
\nPin Mapping (When the Sensor is kept facing you, left most pin is Pin 1)
\nVDD power supply (3.5-5.5V)
\nSDA serial data \u2013 bidirectional
\nNC NC
\nGND
\nPin Identification:
\nNo:\tPin Name\tDescription
\nFor DHT22 Sensor
\n1\tVcc\tPower supply 3.5V to 5.5V
\n2\tData\tOutputs both Temperature and Humidity through serial Data
\n3\tNC\tNo Connection and hence not used
