Access to drinking water has been one of the basic needs of the human being, in addition to being considered a fundamental human right. The measurement, analysis and control in real time and remotely of the parameters that determine whether it is suitable for human consumption has meant a need in water purification systems in rural areas of difficult access. The project has focused on the development of a system for measuring water parameters that guarantee the safety of its consumption, these data are the potential of hydrogen (pH), reduction-oxidation potential (ORP) and parts per million of chlorine residual in water. This system uses an intelligent interface for data transmission in conjunction with the Internet of Things (IOT). The parameters measured in the water are identified as fundamental for the determination of the quality of water suitable for human use, thereby promoting food security in the Central American region. The project has proposed the integration of low cost technologies, low energy consumption, internet of things and long range communication technologies. It was determined that Low Power Wide Area Network (LPWAN) technology and LoRa devices meet the necessary requirements for the execution of the system, in addition, The Things Network platform was used to visualize real-time water parameters and cloud storage. The project presents an innovative proposal for its implementation in rural communities that have water purification systems, with this, it is sought to have greater control and effective management of water purification systems to improve the food security in rural communities of difficult access.
