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 ...

Stop living in the past.

Researchers developed a type of infrared photodiode that is 35% more responsive at 1.55 m, the key wavelength for telecommunications, compared to other germanium-based components. Detecting infrared ...

Flexible NIR and SWIR image sensors combine infrared spectral sensing with conformability, offering new possibilities for wearable healthcare, agriculture, inspection, security, robotics, and ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...
