DHT12 Temperature/Humidity Sensor
DHT12 can be either I2C or 1-Wire (Connect SCL to GND when used as 1-Wire)
DHT12 output calibrated digital signal. It utilizes exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability.
Its sensing elements is 16-bit.
Every sensor of this model is temperature compensated and calibrated in accurate calibration chamber and the calibration-coefficient is saved in OTP memory.
Small size & low consumption & long transmission distance(20m) enable DHT12 to be suited in all kinds of harsh application occasions.
Single-row packaged with four pins, making the connection very convenient
