---

A compact 5V temperature and humidity sensor add-on for Arduino. A product for Arduino that works with official Arduino boards. Suitable for Arduino SCM.

The device has an output calibrated digital signal. It utilizes exclusive digital-signal-collecting-technique and humidity sensing technology, assuring its reliability and stability. Its sensing elements are 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 device to be suited in all kinds of harsh application occasions. Single-row packaged with four pins, making the connection very convenient.
