Design water meter system by using Lora transmission wave

Abstract

Lora Based Water Meter System is build for replace the old physical water meter in Danag city. With this new system the number of water using in every household in the city will be send to the server of the company. So the employees will saved a lots of time because they don’t have to go to every house to collect the number. The output result of this project is a water meter that can measure the flow rate of water and the total amount of water flow through pipe in a certain amount of time. The data will be send to the server throught LoRa transmission wave. The range from the server and the water meter is quite far from 5-10km. It also has a power generator to sustain the power for the system so we don’t need an outside power source for this water meter. The system contains a MCU for data processing, a LoRa for transmiss and receive data, a water sensor for collecting data, a water power generator for power sustain, a LM2596 circuit for decrease the output voltage of the generator from 12v to 5v and the last is a battery for saving power instead of low water flow rate
