Abstract:
The Touch with Operate Relay circuit integrates a touch sensor, comparator IC LM393, and a relay. The touch sensor detects touch, while the LM393 comparator processes the signal. In the absence of touch, the circuit remains inactive, and the LED stays off. When touch is detected, the relay is activated, switching the LED on.
Applications:
Most touch-based circuits use specialized components that increase complexity and cost. This Touch with Operate Relay circuit simplifies design by utilizing readily available components. It’s ideal for projects involving automation, robotics, and educational purposes. The LED stays illuminated as long as the touch sensor detects a touch.
Why This Circuit:
The circuit operates on a DC voltage of 5V, making it suitable for a wide range of devices. The touch sensor allows for intuitive operation, making it user-friendly for learners and hobbyists. The LM393 comparator ensures reliable performance, while the relay provides control over external devices.
Explained Working of Circuit:
The key function of this circuit is to turn on an LED when the touch sensor is activated. The LM393 comparator processes the touch signal, while the relay is used to switch external components. In normal operation, no touch is detected, and the LED remains off. When touch is sensed, the relay is activated, closing the circuit and lighting up the LED.
How to Build:
- Read the included manual thoroughly and review the circuit diagrams and PCB layout.
- Identify and position each component correctly on the PCB.
- Use the color-coding method to identify resistor values and ensure polarity-sensitive components are correctly oriented.
- Solder IC sockets instead of directly soldering ICs to facilitate troubleshooting.
- Test the assembled kit by connecting a 5V DC power source and holding your finger over the touch sensor.
Testing the Kit:
After assembly, connect a 5V DC power source. Hold your finger over the touch sensor – the LED will glow to indicate successful operation. Adjust the resistive value of the variable resistor (R2) to set the desired touch sensitivity.
