Grove magnetic switch

This Grove-compatible magnetic switch helps students understand proximity sensing, reed switch operation, digital input, contact-based switching, smart security systems, and sensor-triggered automation. The commonly documented Grove Magnetic Switch is based on an encapsulated dry reed switch, specifically a CT10 single-pole, single-throw normally open reed switch, which can be actuated by a permanent magnet, electromagnet, or a combination of both.

The StemAids Grove Magnetic Switch is suitable for school STEM labs, Arduino learning kits, Raspberry Pi classrooms, robotics labs, IoT learning spaces, smart door detection projects, magnetic counter models, level detection demonstrations, and embedded-system training setups.

How to Use the Grove Magnetic Switch

1. Connect the StemAids Grove Magnetic Switch to a Grove Base Shield, Grove Base Hat, or compatible digital input interface.
2. Use a Grove cable to connect the magnetic switch module to a digital input port, such as D2.
3. Place a suitable magnet near the reed switch area of the module.
4. Open Arduino IDE, Python environment, or another compatible programming platform.
5. Set the connected digital pin as an input pin in the program.
6. Read the switch state as HIGH or LOW.
7. When the magnet approaches, use the changed signal state to trigger an LED, buzzer, relay, LCD message, robot action, or IoT alert.
8. Move the magnet away and observe the switch returning to its normal state.
9. Test magnet distance and alignment before final project demonstration.
