In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...

The idea behind this compact and economical Vibration Sensor Alarm is very simple. It uses a cheap and cheerful vibration sensor to drive a piezo-sounder. As can be seen in the circuit diagram, it is ...

Useful in out-of-balance occurrences such as those common to home washers/driers, balancing and drilling tools, and pinball machines, the Model TRHN-308 solid-state vibration sensor provides a ...
