Digital relative humidity & temperature sensor RHT03
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
*4 pins packaged and fully interchangeable
2. Description:
RHT03 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 RHT03 to be suited in all kinds of
harsh application occasions. Single-row packaged with four pins, making the connection very convenient.

1) Step 1: MCU send out start signal to RHT03 and RHT03 send response signal to MCU
Data-bus's free status is high voltage level. When communication between MCU and RHT03 begins, MCU
will pull low data-bus and this process must beyond at least 1~10ms to ensure RHT03 could detect MCU's signal,
then MCU will pulls up and wait 20-40us for RHT03's response.
When RHT03 detect the start signal, RHT03 will pull low the bus 80us as response signal, then RHT03 pulls
up 80us for preparation to send data. See below figure:

2). Step 2: RHT03 send data to MCU
When RHT03 is sending data to MCU, every bit's transmission begin with low-voltage-level that last 50us, the
following high-voltage-level signal's length decide the bit is "1" or "0". See below figures:
