Here no one buys any type of equipment, it is very costly and makes you lose money.

Dark Light Detection Alarm – Paper Circuit Project

Abstract: The Dark Light Detection Alarm Paper Circuit Project is a simple, low-cost educational activity designed to demonstrate light-based automation using basic electronic components embedded on paper. The system uses an LDR (Light Dependent Resistor) to sense ambient light levels. When the surrounding area becomes dark, the resistance of the LDR increases, triggering the circuit to activate a small buzzer or LED alarm. This project introduces students to fundamental concepts of sensors, conductivity, and circuit design without the need for a traditional PCB. By using copper tape, coin cells, and compact components, the project provides an engaging, hands-on approach to learning electronics. It is ideal for beginners and helps students understand practical applications of light sensors in security systems, night-based automation, and smart devices.

Package Includes:

  • 1 Piece –Fire Detection Alarm Using an IR Sensor (Working Project Without Battery)

Note:

  1. Project Image only Illustration Purpose. The project may be the same or maybe an improved Version.
  2. We only provide batteries when students pick up their projects from our lab. Batteries aren’t included in shipped orders because our shipping partner doesn’t allow them.
