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 ...

The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.

Krejci’s tutorial video guides viewers on how to construct an infrared camera using an Arduino UNO, an infrared sensor AMG8833, and an 8×8 RGB LED display from SunFounder.

The serial communications is I2C and there’s a tiny optical sensor onboard along with an IR LED. Of course, you could send other keys than media controls.

Defence demand drove the infrared image sensor market to more than $1 billion in 2024, says Yole Group. 2024-30 CAGR will be more than 5%.

The sensor is intended as an alternative to pyroelectric sensors or PIR detectors in home automation, building automation, healthcare, security and industrial applications. Typically human presence ...

OmniVision Technologies, Inc., a leading developer of advanced digital imaging solutions, today announced the OH02A1S—the world’s first RGB-IR medical ...
