Here is an Ultrasensitive Heat Sensor to monitor high temperature in Electronic devices. It can be placed inside the electronic gadget that usually generates heat during its operation. The circuit ...
This circuit uses a thin piezoelectric sensor to sense the vibrations generated by knocking on a surface; eg, a door or table. Basically, it amplifies and processes the signal from the sensor and ...
Accelerometers are used in instrumentation applications to measure a change in velocity with respect to time or an inclination (the angle between an object’s vertical axis and a line perpendicular to ...
When the piezoelectric device (PZT) detects a mechanical impact, it emits a signal that triggers the monostable (IC1), which in turn controls the output of the dual LED/phototransistor opto-coupler ...
