Digital relative humidity & temperature sensor RHT02
1. Feature & Application:
*High precision
*Capacitive type
*Full range temperature compensated
*Relative humidity and temperature measurement
*Calibrated digital signal
*Outstanding long-term stability
*Extra components not needed
*Long transmission distance, up to 100 meters
*Low power consumption
2. Description:
RHT02 output calibrated digital signal. It applys 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(100m) enable RHT02 to be suited in all kinds of
harsh application occasions.

6. Operating specifications:
(1) Power and Pins
Power's voltage should be 3.3-5.5V DC. When power is supplied to sensor, don't send any instruction to the
sensor within one second to pass unstable status. One capacitor valued 100nF can be added between VDD and
GND for wave filtering.
