Notes:
- The response point of the sensor is defined as the moment when the pressure starts to increase from 0 and the resistance value falls below 1MΩ, indicating the sensor is actively “responding” to the pressure. This pressure value is referred to as the “response point”.
- Due to slight variations between batches, devices may exhibit slightly different consistencies. However, through calibration using the program algorithm, the consistency error can be minimized, ensuring accurate and reliable performance.

The HX-01 reference circuit utilizes partial pressure measurement. It involves connecting the pressure sensor in series with resistor R1, with one end connected to VCC and the other end connected to GND, forming a basic voltage divider circuit. The voltage obtained from the division is then connected to Vout.
This circuit allows the sensor’s output resistance change, which corresponds to the pressure variation, to be converted into a voltage change signal. To cater to different application requirements, it is recommended to select an appropriate load resistance R1 ranging from 1kΩ to 100kΩ. It is suggested that the load resistance be set to 50% of the range pressure corresponding to the sensor’s resistance value.
Vout can be connected to a single-chip microcontroller’s ADC interface to detect pressure levels. Furthermore, the MCU’s external interrupt IO interface can be utilized as a pressure trigger function.
