The Solar-Based Insect Killer is an eco-friendly, energy-efficient device designed to reduce insect populations in outdoor environments by utilizing solar energy as its primary power source. The system integrates a 12V, 10W solar panel to harness sunlight and charge a battery bank consisting of three 18650 lithium cells arranged in a 3-cell holder and protected by a 3S BMS module. This configuration ensures stable energy storage and safeguards against overcharging, over-discharging, and short-circuit conditions. The device operates autonomously using a Light Dependent Resistor (LDR) module, which enables automatic switching between day and night modes. During the daytime, the solar panel charges the battery while a green solar LED indicator displays active charging status. At night, the system activates the insect trap, consisting of white and blue 5mm LEDs that attract insects toward a tray containing soap water, ensuring effective and chemical-free insect elimination. A red power LED indicates operational status, while a toggle switch allows manual control. To enhance versatility, the system incorporates a buck converter and a USB mobile charging module, allowing regulated 5V output for auxiliary charging. A 5V single-channel relay module ensures safe switching of the load based on LDR input, while a 1N4007 diode provides protection against reverse current flow from the battery to the solar panel. Mechanical construction includes a robust camera base box, customized fabrication and painting, and secure assembly using screws, nuts, bolts, and 14×36 ribbon wire for internal connections. The insect trap tab and supporting structural components ensure durability and ease of maintenance. Soldering and finishing processes ensure reliability and long-term usability.
KEYWORDS
The Solar-Based Insect Killer system successfully demonstrates the integration of renewable energy technology with practical pest control methods. The project highlights the effective use of a solar panel, battery management system, LEDs, and simple electronics to create a reliable, cost-effective, and eco-friendly insect-killing device. The design enhances sustainability by eliminating the need for chemical insect repellents, thereby reducing environmental pollution and human health hazards. The automatic LDR-based switching mechanism improves usability and ensures uninterrupted nighttime operation without manual intervention. From the testing outcomes, the system proved capable of attracting and trapping a significant number of insects in a short duration, making it suitable for agricultural, residential, and commercial environments. The low maintenance requirements, portable structure, and secondary utility of USB charging add further value to the project. Overall, the project fulfills its objective of providing an affordable, renewable-energy-driven solution to insect control, demonstrating strong potential for real-life implementation.
