In StockAn AC Current Detector is a device or circuit that senses the flow of alternating current (AC) through a wire or appliance. It typically uses components like a current transformer (CT) or hall effect sensor to detect AC current and activate an indicator such as an LED or buzzer.
Description
An AC current detector is designed to detect the presence or flow of AC current in a conductor without making direct electrical contact. It is widely used in electrical safety, troubleshooting, automation systems, and energy monitoring.
There are several methods to detect AC current, including:
- Current Transformer (CT)
- Hall Effect Sensor
- Shunt Resistor + Rectifier
- Inductive Pickup Coil
These detectors can be used for:
- Turning on an alert when current flows
- Detecting power usage in appliances
- Triggering relays for protection or automation
Applications of AC Current Detector:
1.AC Line Status Monitoring
1.Detects whether current is flowing in a power line.
2.Appliance Monitoring
1.Detects if a machine is ON or OFF based on current.
3.Overcurrent Protection
1.Triggers protection circuits when current exceeds a limit.
4.Home Automation
1.Smart switch activates based on appliance usage.
5.Industrial Equipment
1.Monitors operation of motors and heavy machinery.
6.Power Saving Systems
1.Turns off unused devices automatically if no current is detected.

An AND gate can be built using BC547 NPN transistors, a common general-purpose transistor used in digital circuits.
The circuit represents both the inputs A & B for the AND gate and Output, Q, which also has a +5V supply to the collector of the first transistor, which is connected in series to the second transistor, and an LED is connected to the emitter terminal of the second transistor. The inputs A & B are connected to the base terminal of Transistor 1 and Transistor 2, respectively, and the output Q goes to the positive terminal LED.

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.

A Flip-Flop LED Flasher is a simple electronic circuit that alternately turns two LEDs on and off in a continuous loop, creating a blinking or “flashing” effect. It’s commonly built using transistors, resistors, capacitors, and LEDs, forming an astable multivibrator — a basic circuit that oscillates between two states without any external triggering.
It’s often used for decoration, indicators, or learning basic electronics.

A solar-based LED system is a lighting setup that uses solar energy to power LED (Light Emitting Diode) lights. During the day, a solar panel captures sunlight and converts it into electrical energy, which is stored in a battery. At night or in low-light conditions, this stored energy powers the LED light.
These systems are eco-friendly, cost-effective, and ideal for off-grid or outdoor applications like street lighting, garden lights, and emergency lighting.
