4. Working Principle
Thin-film pressure sensors detect pressure by evaluating the change in resistance caused by applied pressure. Their working principle is as follows:
- Power connection : The module is connected to the power supply via VCC and GND, and supports DC 5V.
- Signal output : The resistance of the sensor changes with the applied pressure, and the output voltage signal can be read by the microcontroller.
