HM2303 NEW Digital Humidity Sensor Replace SHT75

Specifications Digital Humidity Sensor Replace SHT75

Calibrated digital signal

Long transmission distance

Low power consumption

  Product Description HM2303 NEW Digital Humidity Sensor Replace SHT75 HM2303 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 HM2303 to be suited in all kinds of harsh application occasions.   Single-row packaged with four pins, making the connection very convenient.     1.
