AM2302

Your specialist in innovating humidity & temperature sensors Standard AM2302/DHT22 AM2302/DHT22 with big case and wires Digital relative humidity & temperature sensor AM2302/DHT22 1. Feature & Application: *High precision *Capacitive type *Full range temperature compensated *Relative humidity and temperature measurement *Calibrated digital signal *Outstanding long-term stability *Extra components not needed *Long transmission distance, up to 100 meters *Low power consumption *4 pins packaged and fully interchangeable 2. Description: AM2302 output calibrated digital signal. It applys exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability. Its sensing elements is connected with 8-bit single-chip computer. Every sensor of this model is temperature compensated and calibrated in accurate calibration chamber and the calibration-coefficient is saved in type of programme in OTP memory, when the sensor is detecting, it will cite coefficient from memory. Small size & low consumption & long transmission distance(100m) enable AM2302 to be suited in all kinds of harsh application occasions. Single-row packaged with four pins, making the connection very convenient. 3.
