Wireless-based pest control in tomato crops

Fruit and vegetable crops are exposed to pests which differ depending on the crop. Particularly, in the case of tomato, fruit flies, when not detected in time, invade the crops leaving larvae that damage them, making the treatment of this pest to be done in a late way, the fumigation is done with backpacks which represents a need for personnel and a greater economic resource. Being the objective to make an early detection and a better treatment in terms of fumigation, we have made a low-cost system that detects and fumigates autonomously tomato crops. Our design is divided into two main segments, the first one an attractant trap, which detects the fruit fly with the help of FC-51 infrared sensors; the second one a spraying system composed of a solenoid valve, a pump and a sprinkler. Both are connected by means of a wireless communicator (ESP32) using the ESP-NOW protocol. Tests of both segments working together were carried out, resulting in a system that, being autonomous and easy to implement, represents an advantage for the grower.
