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 Digital Lock System is an electronic security project designed to control access using a password entered via a keypad. It utilizes an Arduino, keypad, LCD, servo motor, and buzzer to provide a safe, automated locking mechanism. When the correct password is entered, the lock opens; if the wrong password is entered, an alert is triggered. This project is widely used in home security, lockers, safes, and access-controlled systems.

An Electronic Dice is a digital version of a traditional dice, which generates a random number (1 to 6) and displays it using LEDs or a 7-segment display. It uses components like a 555 timer, counter IC (like CD4017), or microcontrollers such as Arduino to simulate dice rolls electronically.

A Battery High-Low Monitor is an electronic circuit or device that detects and indicates the voltage level of a battery — whether it’s too high (overcharged), normal, or too low (discharged). It helps protect batteries from overcharging or deep discharge, which can damage the battery or reduce its lifespan.
These monitors often use comparators, voltage dividers, LED indicators, or microcontrollers to track and display battery status in real time.

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.
