Hall Magnetic Door Sensor 5V DC

What it is: A solid-state proximity sensor module that uses a Hall Effect sensor IC to detect the presence or absence of a magnetic field (such as a magnet attached to a door frame).

Key Specs:

• Operating Voltage: 5V DC (3.3V–5V compatible).

• Output Type: Digital Output (HIGH/LOW logic signal indicating open or closed state) and often an Analogue Output to measure magnetic field strength.

Key Features: Uses non-contact, magnetic sensing—meaning no mechanical moving parts to wear out, offering long life, fast response time, and bounce-free switching.

Common Uses: Door and window status monitoring, security alarm systems, lid/cover open detection, and position sensing in Arduino, ESP32, and Raspberry Pi automation projects.
