Notes:
- The response point is the moment when the pressure applied to the sensor gradually increases from 0. It is at this point that the sensor’s resistance decreases to a level below 1MΩ, indicating the initiation of a “response” from the sensor.
- The consistency between devices from different batches will exhibit a slight improvement. With calibration using a program algorithm, the consistency error can be effectively reduced to within a range of ±15%. This ensures a higher level of uniformity and accuracy across the devices, enhancing overall performance and reliability.

The DF9-16 Flexible Film Pressure Sensor is specifically designed for pressure measurement scenarios on flexible surfaces, making it highly versatile and applicable in a wide range of industries. It finds extensive use in various fields, including smart homes, residential applications, consumer electronics, automotive electronics, medical equipment, industrial control, and intelligent robots.
The DF9-16 pressure sensor utilizes the partial pressure method for measurement. It is connected in series with resistor R1, with both ends connected to VCC and GND, forming a basic voltage dividing circuit. The voltage obtained from the division is then connected to Vout.
The change in the sensor’s output resistance, corresponding to the change in pressure, can be converted into a voltage change signal. To meet specific application requirements, an appropriate load resistor R1 should be selected. Typically, a range of 1kΩ to 100kΩ is recommended, with the load resistance ideally being 50% of the pressure range’s corresponding resistance value.
Vout is connected to the ADC interface of the microcontroller, enabling voltage detection. Additionally, it can be connected to the external interrupt IO port of the MCU, allowing for the utilization of the pressure trigger function.
