Sistem Monitoring Meteran Air untuk Perumahan Menggunakan Mesh Network dengan Protokol MQTT pada Platform Node-RED

Abstract

In human life, water is one of the most important elements because it is often used both for consumption and as a means of hygiene and other life-supporting needs. In general, in Indonesia there are two types of water sources used, namely water sources distributed through piping and other than piping. Water distributed through piping is managed by water supply companies. The company distributes water to customers through pipe connections that are installed with water meters as a means of calculating customer water usage. With this research, the system created can help water supply companies monitor customer water usage in real time remotely by utilizing Internet of Things (IoT) technology without burdening customers to have Wi-Fi in each of their homes. The research conducted obtained water flow data from the YF-S201 waterflow sensor connected to the ESP32 microcontroller. Utilizing ESP-MESH technology to implement Wireless Mesh Network as a sensor communication protocol locally without having to connect to the internet network and utilize its characteristics of self-configure and self-healing so that it can make it easier to build a network of each node. After the data is collected locally, then the data is sent to the MQTT broker through a gateway using the SX1276 long range (LoRa) module the data is transmitted to the LoRa receiver to achieve wider area coverage. Data published to the MQTT broker is then subscribed and displayed on a dashboard built using the Node-RED platform. The results showed an average water volume calculation error rate of 6.73%, data transmission latency from sensor nodes to the gateway averaged 3029.8 ms with a distance of up to 50 meters.
