Full range temperature compensated!
RHT04 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 RHT04/05 to be suited in all kinds of harsh application occasions.
Relative humidity and temperature measurement, calibrated digital signal, outstanding long-term stability, extra components not needed, long transmission distance, low power consumption, fully interchangeable.
