A G-M tube is not the only game in town though, and even the humble photodiode can be pressed into service. [Robert] gives us a good example, with a self-contained radiation detector head that ...

It uses a very small photodiode, and draws so little power it’s perfect for projects with the smallest power budgets. The detector circuit uses a miniature solar cell and a JFET wired up in a ...

A group of South Korean researchers has developed an intelligent fire detection technology that drastically reduces the false alarm incidents, which go off in the absence of a real fire, and is on the ...

Marktech Optoelectronics is one of the world’s leading manufacturers of LED emitter and photodiode detectors with a spectral range from 235nm to 4.3 microns. Light sources include UVC LEDs, UVB LEDs, ...

They are used in TV and AC remotes, heart rate monitoring devices, barcode scanners, motion sensors, smoke detectors, etc. The Aalto University team has developed a photodiode that is 35 percent ...
