It becomes clear that the answer is 'yes' and 'yes' when I look further at it. I'm an Arduino noob and nominally hold a degree in electrical engineering, but I too had the initial reaction of 'Is that right? Is that OK?' to connecting 5V 'straight' to ground. 3 months later I'm benefiting greatly from this thread. Thank you, for your consistently humble and clarifying questions on this. An Arduino is a tremendous tool, and there's a lot of good projects to suit any interests at a given stage. If you do take this on, fellow newcomer, then I hope you're especially interested in learning about more advanced elements of a circuit, or that your process goes more smoothly than mine, or both. So if there's a good model project out there using a piezo buzzer as a vibration sensor, please do link it. Maybe it's because of the first point: because it's hard to tell from observation if your design is a good one, many bad ones persist.

The internet is full of questionable Arduino information, but on this topic more than most. Were the other contributors to the thread convinced of its efficacy, or did they just not want to drag on an argument? Who knows? A beginner lacks the experience to weigh competing views. The design of Post #22 is the only one to receive no objections, so I went with that, but that's not the same as it receiving endorsement.

There isn't a consensus on how to approach this.Īs John noted in Post 10, there are many ways to solve a problem, but here, most of the schematics offered were judged 'wrong.' Not just different or inefficient, but plain 'wrong,' if the goal is to read the sensor while limiting current to the Arduino. Knowing you have it right requires understanding not just the electrical principles, but also the relevant aspects of a piezo buzzer, of multiple kinds of diodes, and of the Arduino board itself. Protecting against frying your Arduino is fundamentally different from many other goals in that you may not want to arrive at a solution by experimenting. I used a motion-sensor as a temporary stand-in and got that running in minutes, compared to the long process here. That doesn't mean you can't do it, but settling on wiring for the sensor took longer than all the other steps combined. Thanks to all who reached out to help here.įor any other newcomers who stumble across this thread, here are my takeaways on using a piezo as an impact sensor: The Gentex 7103 is equipped with a 90 dBA piezo and is tandem for up to 12 units.That does seem to make a difference, and I've marked Post #22 as the solution. It is also fully screened to protect from insects and even comes with a dust cover to guard against contamination. The detector includes a temporal, three-sounding device for evacuation, and a pulsing LED sensing chamber. The detector features a horn frequency of 3100Hz, a fast disconnect wiring harness, and is backed by a one year warranty from the day of purchase. Three position test function makes testing a breeze. It's built to replace older, troublesome alarms with a more reliable, fire protection device. The Gentex 7103 Photoelectric Smoke Detector 120VAC with Temporal 3 Sounder is designed for apartments, homes, hotels, and hospitals.
