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 ...

In winter, it’s important to ventilate living and working spaces regularly. Here’s how to make a homemade measuring station ...

How transimpedance amplifiers are used in fiber-optic communications, laser rangefinders, and LiDAR systems. How avalanche photodiodes enhance TIA performance. Application-specific design and topology ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

An Infrared close object sensor installed on an industrial vehicle detects objects or pedestrians located in a hazardous area. When it detects a problem an audio/visual indicator makes an alert, that ...

This idea describes an MCU interface for a 1-Wire temperature sensor interface that offers high accuracy while using less board space. The circuit can be modified for use with any 1-Wire device. The ...
