Induction Motor Vibration Detection DIY Experiments Science Project Model STEM KIT (Assembled), 100% Tested

Please Note we are only providing kit we marked as ACTUAL PRODUCT, project shown customer needs to do at there own we just provide reference.

Abstract:

The Induction Motor Vibration Detection circuit is built using a piezoelectric sensor and a comparator IC LM393. The piezoelectric sensor detects vibrations, while the LM393 acts as a comparator. In the absence of vibration, the piezoelectric sensor doesn’t conduct, and the LED stays off. When vibrations are detected, the sensor conducts and the LED glows, indicating the presence of vibrations.

Application of the Circuit:

This circuit eliminates the need for expensive or complex vibration sensors by using readily available piezoelectric sensors. The Induction Motor Vibration Detection circuit efficiently activates an LED to indicate vibration, making it ideal for motor diagnostics and automation projects.

Why This Particular Circuit:

Piezoelectric sensors operate efficiently with DC voltages of 5V, which is easily achievable with a DC power supply cable.

Explained Working of the Circuit:

The piezoelectric sensor converts vibrations into electrical signals, which the LM393 comparator interprets to activate the LED in the presence of vibration. The circuit ensures simple operation and reliable performance.

How to Build:

1. Thoroughly read the manual and study the circuit diagram and PCB layout.
2. Solder components as per the PCB layout, ensuring correct positioning and polarity.
3. Use IC sockets for easy IC replacement during troubleshooting.
4. Start from the leftmost corner of the PCB and solder components sequentially.
5. Pay close attention to sensitive components like diodes and capacitors.

Testing the Kit:

After assembly, connect a 5V DC power source. Apply vibration to the piezoelectric sensor to test. The LED should glow when vibrations are detected. Adjust the R2 variable resistor to set the desired vibration detection intensity.
