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 Light Activated Motor Controller using IC 555 is a simple electronic circuit that turns a motor ON or OFF based on the presence or absence of light. It uses a LDR (Light Dependent Resistor) as a light sensor and the 555 timer IC in a comparator mode, along with an LED to indicate the motor’s status.

A Touch ON/OFF Switch is an electronic circuit that allows a device to be turned on or off by simply touching a sensor pad or wire, instead of using a mechanical switch. It works by detecting a small electrical signal from the human body (capacitive or resistive touch) and using that to toggle the output state.
These switches are commonly used in modern electronics, home automation, and DIY projects due to their durability, aesthetic appeal, and user-friendly operation.
