Hall sensor

The Hall Effect Magnetic Sensor Module is designed to detect magnetic fields using a Hall Effect sensor, producing a digital signal when exposed to a magnet. It’s ideal for contactless switching, rotational speed detection, and magnetic proximity sensing in automation and robotics projects.

This module is widely compatible with Arduino, ESP32, Raspberry Pi, and other development platforms. It operates on 3.3V to 5V and features a built-in comparator for stable digital output. When a magnetic field is detected, the output goes LOW, and when absent, it returns HIGH.

Whether you're building a motor speed monitor, a magnetic door sensor, or an encoder system, this module is a reliable and affordable choice.

Key Features:
✔️ Detects magnetic fields using Hall Effect sensor
