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 ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

Electronic enthusiasts may be interested in a new open source infrared sensor which has been created to support both Raspberry Pi and Arduino powered projects. The IR Detector proximity sensor has ...

We’ve featured loads of IR Arduino projects and they are all exciting ... Maybe he will add a temperature sensor someday so it doesn’t have to run on strictly time. A more complicated problem ...

One of the essential parts of any home security system is a door detector that lets you know ... The system here uses a cheap Arduino board, a few sensors, and a magnetic contact switch.

Preventive maintenance Remote temperature measurement of objects heated in a kitchen or in an industrial process The development platform is based on an Arduino-compatible thermal imaging shield. This ...
