A research team successfully implemented CuInSe2 thin-film solar cells composed of copper (Cu), indium (In), and selenium (Se) on transparent electrode substrates. Furthermore, the team developed a ...

A wirelessly powered Internet-of-Things (IoT) sensor system is presented in this paper. It is facilitated by a highly compact, planar electrically small Huygens rectenna. The rectenna is based on two ...

The circuit produces 490…520 mV on 2k load @ 20 mA current through the LED. This is more than enough for several micropower op-amps such as the AD8603/AD8607. The output voltage of the photocell can ...

The recently developed device with a low-cost sensor permits corrections to the dosage of the commonly used painkiller drug paracetamol to improve its efficacy.

This library (with examples) is designed to be integrated in projects using any kind of photocell to retrieve the light intensity (in Lux or footcandles). It handles the GL55xx photocell series but ...

A photocell detects ambient light so lights turn on when it gets dark. A motion sensor activates the light when it detects something moving within its field of view.
