Sensitive and Responsive

I used this to create a simple security alarm for my drawer. The response time is incredibly fast, and it detects even light taps. Highly recommended for beginners.

Great for vibration monitoring

Bought five of these for a school project on structural vibration. They all performed consistently. The ceramic element seems durable enough for repeated testing.

Easy to integrate

The three-pin layout makes wiring very straightforward. Documentation could be better, but there are plenty of tutorials online for piezo sensors that work perfectly with this module.

Perfect for Arduino Projects

This sensor works flawlessly with my Arduino Uno. The analog output is stable, and the sensitivity adjustment pot makes it easy to fine-tune for detecting knocks or vibrations without false triggers.

Works but needs calibration

The sensor works as advertised, but it took some time to get the potentiometer adjusted correctly to avoid noise in the reading. Once calibrated, it performs well.

Good value for the price

Solid build quality for a budget component. It picked up vibrations through the table effectively. Only minor issue is the header pins were slightly loose, but a quick solder fixed that.

5 FAQ

Q: Can this sensor detect sound waves or only physical vibrations?

A: This module is designed primarily for physical vibrations and shocks transmitted through the surface it is mounted on. While loud sounds can cause vibrations, it is not a dedicated microphone for capturing audio signals.

Q: Is this compatible with Raspberry Pi GPIO pins?

A: Yes, it is compatible. However, since the output is analog and Raspberry Pi GPIOs are digital, you will need an external ADC (Analog-to-Digital Converter) like the MCP3008 to read the data.

Q: Can I use this to detect water flow vibration in a pipe?

A: Yes, provided the sensor is securely attached to the exterior of the pipe. It can detect the vibrations caused by fluid movement, though sensitivity will depend on the pipe material and flow rate.

Q: What is the maximum voltage this module can handle before damage?

A: The recommended operating voltage is 3.3V to 5V. Exceeding 5.5V may damage the onboard components. Please ensure your power supply is regulated.

Q: Does this come with mounting screws?

A: No, the package includes only the sensor module. Mounting screws are not included, but the board has standard 3mm holes compatible with common M3 screws.
