Abstract:
The Touch Doorbell circuit is built using a touch sensor, comparator IC LM393, and a relay. The touch sensor acts as the touch detector, while the LM393 comparator processes the signal. In the absence of touch, no signal is detected on the touch sensor, and the buzzer remains off. When the touch is detected, the touch sensor conducts, triggering the buzzer to sound.
Application of the Circuit:
Most touch-based circuits in the market use expensive or complex sensors, but this Touch Doorbell circuit uses a readily available touch sensor, reducing costs and simplifying circuitry. It detects touch and activates the buzzer, ensuring alertness through continuous sound when touch is sensed.
Why This Circuit?
The touch sensor allows easy detection and interaction, making it user-friendly. It operates on a 5V DC voltage, commonly available through USB power, making installation and operation simple.
Explained Working of Circuit:
The primary function of this circuit is to turn ON the buzzer upon detecting touch. The touch sensor converts physical touch into electrical signals. The LM393 comparator processes these signals, activating the relay to control the buzzer. In normal conditions, touch is not detected, and the buzzer remains off. When touch is detected, the buzzer sounds.
How to Build:
- Study the manual, circuit diagrams, and components before assembling.
- Solder components onto the PCB, ensuring correct positioning and polarity.
- Use IC sockets for easy installation and troubleshooting.
- Ensure resistors, capacitors, and diodes are correctly placed and soldered.
Testing the Kit:
After assembly, connect a 5V DC power source. Hold your finger over the touch sensor, and the buzzer will sound. Adjust the sensitivity using the R2 variable resistor if needed. Install the unit in a room to detect touch effectively.
ICs Used:
- LM393: A dual comparator IC commonly used for touch detection circuits.
