My ultimate goal is to make an IoT device that attaches to my washer or dryer and senses the vibration and sends me a text message when the vibration has stopped for a minute or so.
I'm purchased
-Adafruit Feather HUZZAH with ESP8266 module
and two different sensors:
-SW-420 vibration sensor
-analog ceramic piezo vibration sensor module 3.3v/5v
I'm trying to figure out how to attach these modules to the ESP board without overloading it because I understand that the voltage limits are very restrictive and I risk bricking the board if my voltages go too high.
What other electrics would I require?
Also, the piezo has three connectors, +,--, and NC. I played with the sensor with my multimeter connecting it to the + and -- terminals and seeing the voltage spike when i pressed it. I've seen a tutorial where they connected the NC to voltage and put a weight on the piezo, but the effects of these modifications weren't clear to me, should I do this too?
Thanks!
