Product Description
Product Description :
1. Feature & Application: * Full range temperature compensated * Relative humidity and temperature measurement * Calibrated digital signal *Outstanding long-term stability *Extra components not needed
* Long transmission distance * Low power consumption *4 pins packaged and fully interchangeable
2. Description: AM2303 output calibrated digital signal. It utilizes 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(20m) enable AM2303 to be suited in all kinds of harsh application occasions.
Single-row packaged with four pins, making the connection very convenient.
