Abstract
The work aims to create a dependable, effective, and affordable alarm solution that makes use of the characteristics of light-dependent resistors (LDRs). The specific objectives are to design and construct an alarm system that responds to changes in light levels, provide a cost-effective and reliable monitoring solution for various atmospheric applications, and test the device for optimal utilization. The construction process involved assembling electronic components on a breadboard or Vero board. The system's voltage source was a 9-volt battery, and the key components included resistors, capacitors, a transistor, an LDR (Light Dependent Resistor), and a buzzer. LDR was used as the primary sensor to detect changes in light levels, triggering the alarm when the light level fell below a predetermined threshold. The system was tested to ensure its effectiveness and reliability. Different light conditions and intensities are simulated to check if the alarm triggers appropriately. In troubleshooting the constructed light-activated alarm, related to the power source, connections, sensor positioning, interference, or alarm settings to ensure the alarm functions reliably and accurately were identified and resolved. Considering availability, accessibility and affordability the design and constructed light-activated alarm system is a veritable tool that compliments monitoring atmospheric applications in equipment-scarce regions.
