“This product was disappointing. The wires are very fine and weak, a particular problem with a sensor that has to be built into a sturdy mechanical structure. I had pulled a wire out of one of the two I purchased before getting it connected electrically. The documentation for the electronics was very hard to find and incomplete. A search on the part number on the PCB found a completely different Velleman product. Scanning the QR code on the packaging finally found a manual of sorts, but very incomplete. In future, I will stick with AdaFruit and Sparkfun both of whom publish schematics and detailed, well written, use guides.”
