Abstract:
The Automatic Gate Light Control Using LDR circuit is designed using readily available components: an LDR (light-dependent resistor), LM393 comparator IC, and a relay. The LDR functions as a light intensity detector, while the LM393 IC operates as a comparator. When there is sufficient light, the LDR conducts and keeps the LED emergency light off. In contrast, in the absence of light, the LDR stops conducting, activating the relay and turning on the LED emergency light.
Application of the Circuit:
Most LDR-based circuits use specialized and costly light detectors. However, this circuit uses a readily available LDR, reducing costs and simplifying the circuitry. It automatically detects light interruption and activates the LED emergency light when light is absent. Ideal for gate automation and various electronics projects.
Why This Circuit:
The circuit operates over a 5V DC supply, making it efficient and suitable for various setups. Light intensity detection can be easily adjusted by covering the LDR with a hand or other object.
Explained Working:
The LDR-based circuit works as a light detector, while the LM393 IC functions as a comparator. The LDR converts light into electrical energy, which is then processed by the LM393 to control the relay. In normal conditions, when light falls on the LDR, the emergency light stays off. When light is absent, the relay is activated, turning the LED emergency light on.
How to Build:
Read the included manual thoroughly and follow the provided circuit diagrams. Solder components onto the PCB, paying attention to polarity and component placement. Use the 5V DC supply to test, and adjust the resistive value of R2 (variable resistor) to set the desired light detection intensity.
Testing the Kit:
After assembly, connect a 5V DC power source and manually cover the LDR with a hand or object. The LED emergency light should turn on in the absence of light. Install the unit at the ceiling or required location for optimal performance.
Part List:
- Semiconductors:
- U1: LM393 (dual comparator IC)
