Requires a pull-down resistor (10kΩ typical) to form a voltage divider. Operates at safe low voltages (3.3V-5V). Compatible with most single-supply ADC inputs.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect one pin to VCC, the other to an analog input through a 10kΩ resistor to GND. No polarity. For accurate readings, use a 10k-100k pull-down and calibrate for your specific force range. Avoid exceeding 10 kg to prevent permanent damage.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
