This module features a vibration sensor, an adjustable trimpot, and a comparator chip to give an adjustable digital output based on the amount of vibration. The multiturn trimpot can be adjusted to ...

Here’s your useful and beautiful circuit for the day — [New Pew]’s vibration sensor takes manual control of the flip-flop inside a 555 timer and lights an LED in response. Use it to detect those ...

Microcontrollers come in all sorts and sizes, and it’s very tempting to use them everywhere. If you are in a plan to build your own Vending Machine, probably you need a microcontroller-compatible Drop ...

Abstract: The paper describes components of power supply block for wireless sensor nodes powered from harvested mechanical vibration energy which is converted into electric energy. The properties of ...
