In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

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 ...

Is your HDMI cable really pulling its weight? Sure, it's delivering high-definition video and audio, but what has it done for you lately? InjectIR puts the cord to use, sending the IR signal from your ...

A universal sensor transmitter for use in power grid and automotive has been developed by US-based firm Knick. Using an infrared interface, the PolyTrans P 32000 transmitter will recognise the signal ...

I set up my $25 WyzeCam v2 with the PIR Motion Sensor and Sensor Bridge accessory to catch some hummingbirds feeding. I can't use video motion detection because the feeder is constantly swaying in the ...

Extending its portfolio of image sensors for automotive applications, Sony Semiconductor Solutions Corp. has announced the upcoming release of its new 5-megapixel (MP) IMX775 CMOS RGB-IR image sensor ...
