Also compatible with Arduino, Raspberry Pi, and any microcontroller accepting 3.3V–5V logic. The 3-pin header connects easily to breadboards or directly to GPIO pins.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 5V, GND to GND, and OUT to a digital input pin. Use the onboard potentiometer to adjust detection threshold. For microcontrollers with 3.3V logic, powering at 5V is safe as the output drops to 3.3V internally.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
