Hall Effect Alarm
₹210.00
In StockA Hall Effect Alarm is a type of security or position-detection system that uses a Hall Effect sensor to detect the presence or movement of a magnet. When the magnetic field changes (such as a magnet being removed or moved), the circuit triggers an alarm (buzzer, LED, relay, etc.).
Description
The Hall Effect sensor detects magnetic fields and converts them into electrical signals. It’s commonly used in:
- Proximity sensors
- Speed sensors
- Position detectors
- Security systems
In a Hall Effect alarm system, a magnet is placed near the Hall sensor. As long as the magnet is near, the sensor maintains a stable output (either HIGH or LOW depending on sensor type). If the magnet is removed, the sensor’s output changes, which triggers an alarm, such as a buzzer or LED. This type of system is widely used in door security, lock systems, and industrial safety applications.
Applications:
1.Door or Window Alarms
1.Magnet on door, sensor on frame — removing the magnet triggers the alarm.
2.Locker or Safe Security
1.Alarm triggers when magnetic field is disturbed (indicating opening).
3.Speed or Position Sensing
1.Magnet attached to rotating object; sensor detects movement.
4.Industrial Equipment Monitoring
1.Ensures safety by detecting unexpected movement or opening.
5.Bicycle Theft Detectors
Alarm when magnetic lock is tampered.

A Bird Bell is a device designed to either attract, entertain, or repel birds, depending on its purpose and context. Traditionally, it is a small bell-shaped object made of metal, ceramic, or wood, and is usually hung in gardens, balconies, farms, or near bird feeders. Its name comes from its interaction with birds — it may ring when birds land on it, brush past it, or when the wind causes it to move.

A Morse Code Generator is an electronic project designed to convert text input into Morse code signals using Arduino, a keypad, and a buzzer. Morse code is a method of encoding text characters as sequences of dots and dashes, widely used in communication systems, especially in emergency signaling and amateur radio. This project demonstrates signal encoding, microcontroller programming, and interactive electronics.
