Natural mosquito repellent
A student innovation project inspired by the title “Natural mosquito repellent”, structured as a environment & sustainability prototype for hands-on learning, testing and exhibition-ready demonstration.
Project overview
The source document lists the project title “Natural mosquito repellent” but does not include its technical design. Madras Academy interprets the idea within the Environment & Sustainability category and provides a practical educational build path. Students begin with a small safe prototype, connect or fabricate the required subsystems, test the core function, record observations, and refine the design for a final demonstration.

How the project can work
The prototype is designed around the core idea suggested by “Natural mosquito repellent”. A sensing, mechanical, software or control stage captures the relevant input, simple logic or a physical mechanism processes it, and an output such as movement, an alert, a display, a control action or a measured result demonstrates the concept. The exact implementation can be scaled to the student level and available components.

What the project demonstrates
Suggested build plan
Define the problem and success criteria
Research the problem suggested by “Natural mosquito repellent”. Decide what the prototype must sense, move, display, reduce, improve or demonstrate, and define simple measurable success criteria.
Plan the educational prototype
Sketch a block diagram and physical layout. Select only safe, low-voltage or non-hazardous components suitable for a middle / secondary school - beginner / intermediate project.
Build the core subsystem
Assemble the basic mechanical, electronic, environmental or software subsystem first. Verify each part independently before combining the full prototype.
Add control, sensing or user interaction
Connect the relevant sensors, actuators, interface or software logic. Calibrate thresholds and keep the first version simple enough to troubleshoot.
Test with repeatable scenarios
Run several controlled tests, record observations, identify failure cases, and compare results against the success criteria defined at the start.
Refine and prepare the final demonstration
Improve reliability, organise wiring / presentation materials, document limitations, and prepare a short explanation of the problem, solution, results and possible future improvements.

Safety / important note
Use clean, non-hazardous demonstration materials. Do not burn plastics, handle unknown chemicals, culture microbes, or collect contaminated waste without an approved supervised laboratory procedure.
