>> Deutsche Seite
The digital sensor-family from Aosong comprise the models AM2302, AM2320 and AM2322. In one compact housing a capacitive humidity sensor element is combined with an A/D-converter, a digital data processing and a serial communication interface. Beside a high resolution (0.1%RH, 0.1°C) and a low hysteresis a key feature is the factory calibration of each sensor.

For an easy system integration and a reliable signal transmission the communication can be configured in single bus mode or a standard I2C-interface with checksum.
Small size, low power consumption, fast response and an excellent long-term stability make these sensors ideal for application in home and consumer products, industrial control and the Internet of Things "IoT".
Temperature- / Humdity-Sensors AM-2302, AM-2320, AM-2322 are RoHS compliant.
