Resumen

Several countries have implemented automatic meter readings to bill basic services. It requires smart meters and the deployment of communication networks (wired or wireless). Several companies offering basic services still use analog meters. Regarding smart meter implementation in Peru, we find that only electricity companies are currently in the trial stage. And the most advanced implementation is using Power Line Communication (Wired Network). The water service is in the project stage and the gas service does not present information. We propose a module that takes a picture of the meter's counter, packages the data, and sends it over a LoRa Network to a Gateway. We implement a LoRa multi-packet protocol prototype for image transmission. The Multi-Packet protocol assigns bytes from the LoRa sub-packet to be the header of the packet, this header gives information to improve efficiency. Sending packets in batches improves energy consumption and time transmission because the sender does not have to wait for an ACK response. This work is the first step in a surveillance system, and gives information about image transmission using LoRa.
