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:

HM2301 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 HM2302 to be suited in all kinds of harsh application occasions.

Single-row packaged with four pins, making the connection very convenient.
