Environmental Variable Monitoring with IoT Technology

This article describes the design of a flexible and low-cost platform for monitoring environmental variables applied to agriculture. For the construction of this platform, technologies based on the communication protocol, Wi-Fi, Bluetooth, and Zigbee were used, using the embedded Raspberry pi 3 b + system and sensors to quantify different environmental variables, using different open source hardware and software tools. The network is made up of a central node (gateway), implemented on Samsung's Artik 1020 card, and two nodes where the sensors for reading environmental variables are connected. Finally, the data is collected by the gateway, which will be in charge of processing and storing it in a database so that the user in the future can access the information in real time from anywhere.
