Smoke detector with gas sensor TGS 813 – source. The simple schematic diagram of a smoke detector presented here utilizes the gas sensor TGS 813 as the main detecting component. The circuit is pretty ...

This simple water detector circuit uses alternative voltage in order to prevent the corrosion of the electrodes. It is easy to build and uses N1 as a trigger Schmitt gate which generate the AC. If ...

The beginner’s guide for hobbyists and makers unlocks some of the practical secrets behind lightning detection design.

Looking for a light project to teach young hackers some very basic electronics? Here’s a quick and easy weekend project, a simple metal detector! We all know 555 timers are very useful and po… ...

When you think of a radiation detector, you’re probably thinking of a Geiger tube and its high voltage circuitry. That isn’t the only way to measure gamma radiation, though, and [Alan] … ...

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.

Detector design and device fabrication. In order to combine diamond nanophotonic circuits with superconducting single-photon detectors, we fabricate niobium nitride (NbN) nanowires directly on top ...
