In this CD4017 project, I have shown how to make a simple motion sensor switch using 4017 IC and E18-D80NK IR proximity sensor to automate the washroom light. You can also use this circuit as a motion ...

Have you ever noticed how shopping malls, parking lots, or event venues seem to track the number of people or cars present inside? You might think they use an AI camera to count them, but in reality, ...

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 ...

An IoT-enabled system designed to automate water dispensing and refilling using Arduino, IR sensors, and water level sensors. This project ensures efficient water management by eliminating manual ...

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 ...

Agile Analog has added a customizable IR drop sensor to its IP library, providing chip designers with real-time monitoring of voltage drops. These drops can be caused by power supply fluctuations, hot ...

Infineon’s PASCO2V15 CO2 sensor is a compact and precise carbon dioxide sensor that uses photoacoustic spectroscopy (PAS) leveraging its built-in microphone and IR emitter to detect CO2 levels by ...
