This project aimed at designing and implementing a module for taking readings of electrical energy consumption, which at this moment are being transmitted to a web server by using the current mobile internet access technologies -GSM and IoT- allowing the client to have access to his information with a login to enter the readings -user name and password-. Its operation is based on the use of a microcontroller card that has been unified to some previously calibrated voltage and amperage measurement devices, so that it makes a comparative measurement of these values in the ongoing operation. Finally, the data is sent to the server that is hosted on the web by means of a GSM connection module associated to a SIM card that has been registered previously with any of the mobile service providers in operation in the country. This article explains the design and operation of a module whose main objective is to take the true value of a power consumption measurement. The transmission of the data from the data transmission module to the dedicated server was correctly and continuously generated in the multiple tests performed over a long period of time. Likewise, the technology that was implemented for the transmission of the data -GSM- proved to be the most feasible choice in terms of infrastructure and scope in the implementation of the project, due to the great acceptance that this technology has in the country, since it saves costs in the implementation of a communication network.
