Bright -Love them!

Excellent lights, we'll see how long they last.

Used to Monitor Noise / Vibration Levels

Use these to replace vibration sensors in a monitoring project

work as expected

These seem to work well, just check each one to verify at same setting of amplification if using in an array, only thing that is a little disappointing is the frailness of the mic leads -- so I need to make a case for these to prevent breakage

Still a pretty good value even at that

these are niftly little sensors. I've used them to activate lights in my arduino project. Of the 5 it appears I got one dud, which seems not to work at all. Still a pretty good value even at that.

Five Stars

Product worked as it should.

ombir singh
wide sensitivity range & stands up to abuse

used as a redundant safety feature for a machine that has to stop if it hits something. It was easy to adjust the knob until it only triggers when there is a very loud sound. The led made tuning very easy to do! I was also impressed that one of these things still worked after I plugged it in backwards by mistake. It got hot but didn't burn up right away.
