HM2301 Digital-output humidity and temperature sensor Data sheet
HM2301 Digital-output humidity and temperature sensor
Feature & Application:
- Full range temperature compensated
- Relative humidity and temperature measurement
- Calibrated digital signal
- Outstanding long-term stability
- Extra components not needed
- Long transmission distance
- Low power consumption
- 4 pins packaged and fully interchangeable
Description:
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 DHT21 to be suited in all kinds
of harsh application occasions.
Single-row packaged with four pins, making the connection very convenient.

Step 3: HM2301send data to MCU
When HM2301 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".
