سنسور دما و رطوبت AM2302

The AM2302 is a basic, low-cost digital temperature and humidity sensor.

Its sensing elements are connected with an 8-bit single-chip computer. Every sensor of this model is temperature compensated and calibrated in an accurate calibration chamber and the calibration-coefficient is saved in a type of program in OTP memory when the sensor is detecting, it will cite coefficient from memory. Small size and low consumption & long transmission distance(100m) enable AM2302 to be suited in all kinds of harsh application occasions. Single-row packaged with four pins, making the connection very convenient.

They consist of a humidity sensing component, an NTC temperature sensor (or thermistor) and an IC on the backside of the sensor. For measuring humidity, they use the humidity sensing component which has two electrodes with moisture holding substrate between them.

There is also a very basic chip inside that does some analog to digital conversion and spits out a digital signal with the temperature and humidity. The digital signal is fairly easy to read using any microcontroller.

* Welding temperature should be below 260Celsius.

* Avoid using the sensor under dew condition.

* Don't use this product in safety or emergency stop devices or any other occasion that failure of AM2302 may cause personal injury.
