In this project, it is presented the implementation of an autonomous monitoring system using solar panels and connecting to the network through Wi-Fi. The system will collect meteorological data and transmit in real-time to the web for the visualization and analysis of the results over temperature, humidity, and atmospheric pressure. The system will allow saving time and money, employing decision making and efficiency. For the development of this device, a small platform "Wemos D1" for the internet of things allows easy programming in the platform "Arduino IDE".
