Microcontroller Based System for Detection of Harmful Chemicals on Fruits and Vegetables

Abstract

Abstract: Resources are getting limited with the increasing population. The incessant drive to meet food demands compels farmers to augment crop production using both natural and artificial means, including chemical fertilizers and pesticides. While these substances safeguard crops against pests and fungi, their excessive use compromises food quality and poses health risks due to their infiltration into the food chain. Recognizing this issue, there is a pressing need for a portable device capable of analyzing the organic composition of edibles. This study endeavors to ascertain both organic and inorganic elements present in food items, empowering consumers to make informed choices about their consumption. Central to this research is the development of an electronic device utilizing infrared technology to detect chemical residues. By displaying the ratio of organic to inorganic components, consumers can utilize this data as a guideline for selecting safe-to-consume food products,here we are proposed a portable device which makes it easy to identify whether the fruit is organic or inorganic based on this consumer can conclude what to eat and what should not eat.
