IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...

STMicroelectronics has introduced a multi-spectral ambient light (plus UVA and near-IR) sensor, with flicker detection, in a package smaller than 1mm x 2mm. Applications are foreseen with phone ...

Some readers may recall building a line-following robot during their school days. Involving some IR LEDs, perhaps a bit of LEGO, and plenty of trial-and-error, it was fun on a tiny scale. Now imagine ...

As you might have noticed, the 38-KHz pulse generator is built around the evergreen timer chip NE555P (IC1). Here, the RC components (R5-C3-P1) set the astable frequency to drive the infrared light ...

The FOT variants of the KCI 1300 inductive encoders from Heidenhain can also serve as a bearing cover. A growing trend in encoder technology is the integration of additional sensors to add diagnostic ...

Optical or magnetic linear encoders are traditionally used to provide position feedback in applications with frequent product changes or and sophisticated machining. Linear encoders improve the ...
