Pesticide detection in fruits and vegetables is an important aspect of food safety. A small amounts of pesticides may remain in or on fruits, vegetables, grains which is negative impact on human health. It is important to monitor and regulate their use to ensure safe consumption of these foods. In this paper we proposed a system to detect the pesticide on fruits as well as vegetable. The system consists of different types of sensors such as ethylene gas ,PH and temperature sensor and Node MCU microcontroller. Pesticides are stated to be present in fruits if they are detected to be in a range above or below the threshold level. The pesticide content and values received from each sensor are displayed in the Blynk APP via IoT. The proposed system have the potential to provide a more efficient and accurate way of detecting pesticides on fruits and vegetables.
