While learning about different types of vibration sensors for condition monitoring, I came across a cheap piezoelectric shock/tap/vibration sensor switch module hiding in a corner of my messy ...
Piezo Trigger Switch circuit described here is a microcontroller-compatible shock/impact sensor switch module works on 5VDC supply. The whole circuit can be assembled on a 5×7 cm common circuit board.
A 1-op-amp circuit for processing the signal from a piezoelectric accelerometer. Accelerometers are used in instrumentation applications to measure a change in velocity with respect to time or an ...
