A3144 Hall Effect Magnetic Sensor Module
—An A3144 Hall effect sensor module detects the presence of a magnet and outputs a digital signal, with no moving parts to wear out.
Specifications
- A3144 Hall effect switch
- Digital output — magnet present or absent
- 3.3-5V supply
- Indicator LED
- Responds to one magnetic polarity
What you can build with the A3144 Hall Effect Magnetic Sensor Module
- Wheel and shaft rotation counting
- Door and lid position sensing
- Water meter pickup
- Contactless limit switches on machinery
Compatibility
Works with Arduino, ESP32, Pico and Raspberry Pi on a digital input. Unlike a reed switch it has no contacts to bounce or wear, which matters for high-speed counting.
Shipping
Dispatched from New Zealand with courier delivery nationwide, including rural addresses. Prices are in New Zealand dollars.
