Perfect for prototyping acoustic sensors

This kit made it incredibly easy to set up a piezoelectric microphone. The shielded wire really helps reduce noise, and the charge amplifier module works flawlessly right out of the box.

Excellent signal clarity

The signal-to-noise ratio is impressive for such a compact module. I used it to detect subtle tapping sounds, and the output was clean and easy to process with my microcontroller.

Fast shipping and quality product

Arrived quickly and packaging was secure. The sensor film shows no signs of degradation after weeks of continuous testing in our lab environment. A solid choice for precision sensing.

Good integration with Arduino

Works well when connected to an Arduino Uno. The documentation could be slightly more detailed regarding gain adjustment, but once figured out, it performs exactly as described.

Great value for research projects

Bought this for a university project on vibration monitoring. The film is very flexible and sensitive. Only giving 4 stars because the soldering pads are quite small, requiring a steady hand.

5 FAQ

Q: Can this sensor detect underwater pressure changes?

A: While PVDF film is inherently resistant to moisture, this specific kit is not IP-rated for submersion. It is designed for air-based applications like vibration, impact, and acoustic sensing.

Q: Does this kit come with a power supply?

A: No, the kit includes the sensor film, shielded wire, and the charge amplifier module. You will need to provide a suitable DC power source (typically 3.3V or 5V) depending on your specific circuit design.

Q: What is the maximum frequency response of the LDT0-028K?

A: The PVDF film itself has a very wide frequency response, often extending into the MHz range. However, the overall system bandwidth will depend on the configuration of the external charge amplifier circuit you build or use.

Q: Is the shielded wire pre-soldered to the film?

A: Yes, the sensor film comes with the shielded coaxial cable already attached at the factory to ensure optimal connection integrity and minimize handling damage during assembly.

Q: Can I cut the film to a smaller size?

A: We do not recommend cutting the active area of the film as it may alter the electrical characteristics and sensitivity. If you need a different size, please check our catalog for other model variants.
