When a magnet comes within range, the reed switch closes, completing the circuit and triggering the connected device. This is the standard configuration for door sensors, proximity alarms, and automation triggers.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I adjust the sensitivity of the PS-3150 magnetic reed sensor?\u003c\/h4\u003e\n\u003cp\u003eA: The PS-3150 features an adjustable design that allows you to reposition or fine-tune the sensor relative to the magnet source. By adjusting the mounting distance or angle, you can control at what proximity the switch activates, giving you flexibility for different project setups and enclosures.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is the PS-3150 compatible with Arduino, Raspberry Pi, or other microcontroller platforms?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The PS-3150 normally open magnetic reed sensor outputs a simple switching signal that is compatible with most microcontroller platforms including Arduino and Raspberry Pi. It integrates easily into GPIO-based circuits for proximity detection, door monitoring, or any switching application.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How many sensors come in one order?\u003c\/h4\u003e\n\u003cp\u003eA: The PS-3150 is available in three quantity options: 1 piece, 5 pieces, or 10 pieces.
