This home smoke detector circuit warns the user against fire accidents. It relies on the smoke that is produced in the event of a fire and passes between a bulb and an LDR, the amount of light falling ...

This infrared detector circuit uses a passive IR-detector component PID20. It converts heat radiation into electrical impulses. The output voltage of the PID20 increases when an object comes close to ...

There are many ways to build a radio receiver, but most have a few things in common, such as oscillators, tuned circuits, detectors, mixers, and amplifiers. Put those together in the right order an… ...

Microchip’s TC54 series of voltage detectors are well-suited for battery powered systems because they can operate on current as low as 1 µA. To view the application note, click ...

The circuit in Figure 1 can detect an overcurrent condition and send an alarm signal to the ECU within 100 ns. The circuit employs an AD8214 high-voltage threshold detector.

This circuit was developed to aid manufactures of optical equipment in using linear detectors arrays with their optical setup without requiring specialised knowledge of electronics. These circuits ...
