Abstract: This study describes the development of a tele–operation and remote monitoring system for a prototype of water purification based on photovoltaic solar energy. The implementation was carried out by integrating web service, artificial vision technologies and free software with the objective of taking a photographic capture of a multi–parameter Hi 9813–6n Hanna instruments device (responsible for measuring parameters related to water quality inside the water maker) and process the images to present data in alpha–numerical format in real time through a web application including also evidence of image processing, character recognition and the status of the multiparameter battery. The system performed the image processing and subsequent character recognition by implementing the OpenCV library under the Python language and allowed real–time access to information to multiple users from any point connected to the internet through a Node.js web application displayed on the Heroku infrastructure, additionally, video transmission was presented in the web application in order to know the state of the system and analyze its behavior in a more comprehensive manner.
