WitBlox Magnet Sensor Kit - 6 Projects, Hall Effect Switch Module
WitBlox DIY Magnet Sensor Kit – 6-in-1 Projects with Hall Effect Sensor Module
The WitBlox DIY Magnet Sensor Kit is a 6-in-1 project kit designed to teach magnetic sensing using a Hall effect sensor module. It includes all components needed to build six different projects ranging from a magnetic door alarm to a rotation counter. This hands-on kit is ideal for students, hobbyists, and educators exploring electronics and sensor technology.

What You Can Build With This
- Magnetic Door Alarm – detects when a door opens using a magnet
- Rotation Counter – measure RPM of a rotating wheel with a magnet
- Proximity Detector – sense the presence of a magnet nearby
- Magnetic Switch – replace a physical switch with a magnet-activated control
- Intruder Alert – set up a magnetic tripwire for security
- Simple Hall Effect Demo – demonstrate magnetic field detection with an LED
Compatibility
This sensor module works with any microcontroller that accepts digital input, including Arduino Uno, Nano, Mega, Raspberry Pi, ESP32, and the WitBlox app development board. It operates at 3.3V and 5V logic levels, making it compatible with most starter kits. Pair it with a WitBlox Bluetooth module for wireless alerts.
Wiring Notes
Connect VCC to 5V (or 3.3V), GND to ground, and DO (digital output) to a digital input pin on your microcontroller. The output goes LOW when a magnetic field is detected. A 10K pull-up resistor is often included; if not, enable internal pull-up on the reading pin. Keep leads short to avoid false triggers.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, the sensor operates at 5V and provides a digital output that can be read by any Arduino digital pin. Example code is included in the kit guide.
What magnets are included?
The kit includes 2 small neodymium disc magnets sufficient for all six projects. They provide a strong trigger for the Hall effect sensor at close range.
Can I use this to count rotations?
Absolutely. Place a magnet on a wheel and position the sensor nearby; the digital output toggles with each pass, allowing your microcontroller to count pulses.
📦 Free Setup Handoff Document Included
