An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

Controlling an LED with Arduino Using an IR Sensor An Infrared (IR) sensor is a commonly used device for proximity detection and object sensing. When combined with an Arduino and an LED, it can create ...

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 ...

O. What is RelayModule Library? If I use it, how easier life will be ? If you have made some Arduino project with Relay Modules, you probably wrote some scattered code for relays. Scattered Code ...

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 ...

The damages that can be done by fire are devastating. To prevent causalities or damages, it is necessary to detect the fire, so that warnings can be provided and even automatic fire suppression ...

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 ...
