The SS49E Linear Hall Effect Sensor is a compact analog magnetic sensor used to detect the presence and strength of a magnetic field. Unlike simple on/off switches, its output changes proportionally with the magnetic field, which makes it a favorite for hobbyists, students, and makers building position, speed, and proximity sensing circuits. It suits electronics projects, robotics, Arduino and microcontroller builds, and small automation systems.
Key features
- Linear (analog) output that varies with magnetic field strength.
- Model SS49E, a widely recognized and easy-to-source sensor.
- Small footprint that fits neatly on breadboards and custom boards.
- Simple wiring, friendly for beginners and experienced makers alike.
- Commonly compatible with popular microcontroller platforms.
Typical uses
- Measuring rotor or wheel position and rotation in DIY projects.
- Contactless proximity and presence detection using a magnet.
- Current and field sensing experiments for learning electronics.
- Robotics, RC, and small automation feedback circuits.
How to choose / tips
- Confirm the SS49E fits your project's input voltage and signal range.
- Pair it with a small permanent magnet for reliable readings.
- Keep the sensor face aligned toward the magnet for the best response.
- Order a spare for prototyping, since sensors are easy to swap.
