    The continuous progress of technology and the application of the Internet of Things (IoT) in the agricultural sector has allowed an advance in the systems that favor the development of crops. This project develops a control and monitoring system for the cultivation of vegetables under greenhouse in the Huachi Grande parish of Ambato. The objective is to provide the grower with an autonomous system capable of making intelligent decisions without the need for constant supervision by a person. The system allows monitoring and control of temperature and humidity, as well as pH levels and the amount of radiation that the plants receive during the day, and also has an artificial lighting system. The purpose of this research work is to provide a favorable environment for cultivation inside a greenhouse, for this we work with temperature and humidity sensors, soil moisture sensors, pH sensor and solar radiation sensor. In order to control the temperature inside the greenhouse, two fans and an automatic curtain closing and opening system by means of a low-speed electric motor are used, as well as soil humidity control, which is carried out by means of drip irrigation. On the other hand, for pH monitoring, a sensor is used for the water that enters the crop through the irrigation hoses. Finally, a solar radiation sensor is used to monitor the amount of radiation received by the plants, in order to activate artificial lighting, if necessary, with the objective of increasing the period of time during which the plant performs photosynthesis. The technology used is based on LoRaWAN and the MQTT protocol. The system has two Lora nodes and a gateway to communicate with the server and connect the system to the Internet. To control the system, an HMI based on Node-RED is used, which allows constant real-time monitoring, automatic or manual control of the system and visualization of daily statistics. In addition, the system has a control and monitoring through the Telegram application, through which the producer receives alert notifications and can control the system manually.
