An automatic mosquito detection and spraying system.

Abstract

Malaria is life threatening disease caused by parasites that are transmitted to people through bites of infected female Anopheles mosquitoes, it attacks a person’s red blood cells. Malaria remains one of the leading problems of developing countries, and Uganda bears particularly large burden of the disease. This report describes the development of an automatic mosquito detection and spraying system which sprays mosquito insecticide in the room upon detection. A number of research mechanisms were utilized in collecting the kind of data needed to achieve the objectives of the project, the major one was document review which involved reading documentaries whose major source was text books, journals, magazines and newspapers from different scholars and researchers. In this system, highly sensitive condenser microphone is used to collect sounds produced in its surrounding space and conducts output process by electrically converting the collected sounds into collected sound signals. Amplification and filtering was carried out on the collected sound. The collected sound signals was fed to the microcontroller 328p to be processed so that to extract a specific frequency component corresponding to the frequency band of the buzzing sound of mosquito and conducts detection process whether the mosquito exists in space or not based on the extracted signal. In case the mosquito is detected the motorized pump will be activated to spray the room for the given period of time. The liquid crystal display is used to display sound data from the microphone sensor. The ultrasonic sensor is used to determine whether the insecticide in the reservoir is low in order to activate the alarm as a sign that the reservoir needs to be refilled. The developed system ensures that the mosquitoes are detected and room is sprayed immediately to kill them. The system has been tested, validated and proven to work.
