AM2311A (an upgraded version of DHT22) digital temperature and humidity sensor provides calibrated digital signal output. AM2311A digital temperature and humidity sensor use special temperature and humidity acquisition technology to ensure that the product has high reliability and excellent long-term stability.
The AM2311A digital temperature and humidity sensor is composed of capacitive humidity elements and integrated high-precision temperature measurement equipment and is connected to a high-performance microprocessor.
If the sensor is surrounded by volatile solvents, irritating tapes, adhesives, and packaging materials, the reading may be higher. For more information, please refer to the relevant documents.
The AM2311A includes a capacitive humidity sensor and a high precision temperature sensor. The range of humidity sensor is 0 to 99.9 %RH with ±3% accuracy while the temperature sensor ranges from -40 to 80℃ with ±0.5℃ accuracy.
Calibration coefficients are stored in the form of a program in the single-chip computer. These calibration coefficients are called in the process of processing the detection signal inside the sensor. A standard single bus interface makes system integration easy and fast. The standard single bus interface makes system integration easy and fast. Ultra-small size, very low power consumption, Signal transmission distance can reach more than 20 meters. Products are cited as 3Wire (single bus interface) the connection is convenient. You can download the Datasheet
