Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

This project-based on Arduino Uno and IR sensors is used to automatically switch on and switch off a washroom’s light that works on AC mains. Whenever a person enters the washroom, the light bulb (or ...

Infrared line tracker modules hardly need an in-depth explanation as they’re very familiar to most electronics and robotics hobbyists. In this post I’ll discuss a popular and cheap infrared line ...

A Hall effect sensor or Hall sensor is a magnetic non-contact sensor that generates an electrical signal proportional to the magnetic field applied to it. Hall effect sensors are widely used in ...

Adding cameras and vision algorithms to your projects and robots might sound cool but sometimes it becomes expensive in terms of both capital and time. When the task at hand is much simpler like ...

If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...
