Sistema de control y monitoreo de riego, purificación de aire y fumigación para la plantación de tomate de riñón en invernaderos mediante dispositivos IOT en la agropecuaria San Miguel de Salcedo

Abstract

The development of this research project has the purpose of building an automated system for the control and monitoring of irrigation, air purification and fumigation in kidney tomato plantations in greenhouses through IoT devices, which is made up of an irrigation system that it activates automatically when the soil humidity is less than 50% to keep the planting in optimal conditions, a system capable of controlling the level of CO2 found in the environment was also made thanks to the air extractors integrated by motors that raise the curtains for the circulation of clean and fresh air, in addition to conditioning the temperature inside the greenhouse. Likewise, a fumigation system was built using sprinklers that were programmed to activate once every 15 days for and when the white mosquito is detected, this was done through valves and the pumping of insecticides by the water pump to counteract the damage caused by the pest. All these events are controlled by the ESP32 microcontroller and monitored by the IoT platform created in Home Assistant together with the ESPHome services that are complements to the server for monitoring measurement variables through a dashboard, configured within the platform, all These data are transmitted through a WiFi network, for decision making towards the actuators. The system was developed due to the lack of technology that exists in kidney tomato greenhouses in the canton of Salcedo.
