This project automates a car parking system using an Arduino Uno, IR sensors, a servo motor, and an I2C LCD display. It detects vehicle entry and exit, manages parking slot availability, and displays ...

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 ...

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 ...

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, ...

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 ...

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 ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

Intrusion Detection Systems (IDS) strive to catch computer system intrusion & utilize by any garnering and analyzing data. Wireless IDSs garner all local wireless transmissions and generate alerts ...

This solar tracker system uses the Arduino UNO board, a servomotor, 2 LDRs and 2 resistors to rotate the solar panel towards the Sun or a source of light. Here https ...
