Key Features of Hall Effect Sensor Module

Non-Contact Magnetic Detection: Senses the presence or absence of a magnetic field without physical contact, enabling wear-free, long-life operation.
Clean Digital Output: Onboard LM393 comparator provides a crisp HIGH/LOW signal - no debouncing or complex analog processing needed.
Dual LED Indicators: Power LED confirms module is energized; signal LED lights up when a magnetic field is detected for instant visual feedback.
Wide Voltage Compatibility: Operates reliably at both 3.3V and 5V logic levels, making it plug-and-play with virtually any microcontroller platform.
Ultra-Fast Response: Microsecond-level switching enables high-speed RPM measurement and real-time position sensing applications.
Compact & Mountable: Small PCB footprint with an M3 mounting hole allows easy integration into enclosures, motor housings, and mechanical assemblies.
Sensitivity Tuning: Onboard potentiometer (on applicable variants) lets you fine-tune the detection threshold for different magnet strengths and distances.
Beginner-Friendly: Simple 3-pin digital interface requires no external components; connect and start reading in minutes.
Reliable & Durable: No mechanical contacts mean no wear, no bounce, and virtually unlimited switching cycles.
Versatile Detection: Works with neodymium magnets, ferrite magnets, and even electromagnetic coils for diverse applications.

Perfect For

RPM / Speed Measurement: Mount a magnet on a motor shaft or wheel spoke and count pulses per revolution to calculate RPM - perfect for tachometers, fan speed monitors, and vehicle speedometers.
Door / Window Security Alarm: Attach a magnet to the door and the sensor to the frame; trigger an alert or buzzer whenever the door opens and the magnetic field disappears.
Contactless Proximity Switch: Replace mechanical buttons with a magnet-activated switch for waterproof, dustproof, and tamper-resistant control panels.
Flow Meter Pulse Counter: Pair with a water or gas flow sensor that uses a magnetic rotor to count flow pulses and

How It Works

The Hall Effect Sensor Module operates on the Hall Effect principle: when a magnetic field (specifically the south pole of a magnet) is brought near the sensor IC, it generates a voltage proportional to the field strength. The onboard LM393 comparator converts this analog response into a clean digital output - LOW when a magnet is detected and HIGH when it is absent. Simply connect VCC, GND, and the digital output pin to your microcontroller, and you can instantly read magnetic presence in your code. Attach a small magnet to a rotating shaft, a door, or a moving part, and the module becomes a versatile proximity, speed, or position sensor.
