Apple Pesticide Detection and Alert System

Many modern techniques were developed to produce more quantity of food for growing population. Now a day fruits and vegetables have become the major source of nutrients and energy. Many chemicals are used in the production of fruits and vegetables, which are dangerous for consumers. To identify pesticides in organic fruits and vegetables, it is necessary to build low-cost, portable, sensitive, and selective biosensing platform. Many sensors like nano-sensors, pH sensors, humidity and temperature sensors and gas sensors are used to detect the pesticides on the fruits and vegetables. The input data is taken from sensors and send to the microcontroller where the program is written in such a way that it calculates the amount of pesticide present on fruits and display the output. The software for this project is written in Arduino c program. The safe value of pesticides in fruits or vegetables which can be consumed by humans and animals are mentioned in the Arduino c program. If the pesticide content is above or below the threshold level then the sample contains pesticides. Developing an alert system that triggers messages when pesticide levels surpass predefined thresholds. The message is sent through proper communication channels such as SMS to the stakeholders such as farmers, distributors, retailers, and consumers by using GSM modem.
