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 ...

LED chip maker Taiwan-Asia Semiconductor (TAS, renamed from Opto Tech) is the exclusive supplier of short-wave infrared (IR) LED devices used in the body temperature sensor of Apple Watch 8, according ...

Most consumer remote controls operate using infrared light. This works well assuming the piece of equipment has a line of sight to the remote. But if you have, say a receiver in a cabinet or closet, ...

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object being ...

Proximity detection adds many smart features to the devices we use.For example, when making a call with a phone held to your ear, face detection using proximity sensing can disable the touchscreen and ...

Omron Electronic Components has introduced a non-contact MEMS thermal sensor that it claims can detect the presence of humans in an area without the need for movement. The sensor is intended as an ...

I needed a multichannel line tracker sensor module for an upcoming project. A quick search found several versions of infrared line tracker sensor modules that met or exceeded my demands, but I picked ...
