The Magnetic Door/Window Reed Switch Sensor is a compact and reliable proximity sensor designed for monitoring access points in homes, offices, and DIY projects. Operating on the principle of a magnetic reed switch, the circuit remains open until the magnet is brought close, at which point it closes to allow current flow. This makes it perfect for integration with microcontrollers like Arduino, enabling digital monitoring with the use of a pull-up resistor. With a reed switch size of 11 × 16 mm, magnet size of 11 × 15 mm, and a 35 cm cable, this sensor is lightweight, easy to install, and highly effective in alarm systems, automation, and access monitoring.
