## Questions & Answers

**Q: Can I attach these to a washing machine and a dryer to detect if they are running?**
A: Very possible but why!

**Q: what is the a minimum force threshold be configured? For example, can it be set to identify detect a 25 kN of force of higher?**
A: ANSWER IS NO!. 12 kn of force, would not work with a piezoelectric element. This control is for small vibrations like knocking on door or awning that wind swings in the breeze.

**Q: How sensitive is this sensor?  For example, if I put this inside a model railroad freight car - would it be able to sense if the car is moving or not?**
A: Absolutely, Sub-G reading capable...will detect rail car motion via vibration. 

Problem you’ll have to surmount is they are so sensitive, discriminators in the code will be required to remove the noise of the car standing still, as well as other vibrations from near by things. 

Good luck

**Q: Does this produce some square wave matching the vibration, or does the output just remain on for a period of time once it detects a vibration?**
A: Yes. You may use counter to determine number of vibrations by logging pulses.

Device does what it should, the adjustment is VERY sensitive. Signal is very brief, but if you’re looking for a quick trigger DO, this does the job
