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 ...
Researchers at the Indian Institute of Technology (IIT) Bombay have successfully made low-cost piezo-resistive vibration sensors using polyurethane foam coated with carbon nanomaterial-based ink.
