This manual describes the HAC-MLW wireless remote meter reading system, including the HAC-MLW module and HAC-GW-MLW gateway for LoRaWAN applications.
The HAC-MLW wireless remote meter reading system integrates data collection, two-way communication, and meter control. It complies with the LoRaWAN 1.0.2 standard protocol and consists of the HAC-MLW wireless meter reading acquisition module, a LoRaWAN gateway, and a LoRaWAN billing system (cloud platform). Key features include ultra-long distance communication, ultra-low power consumption, high anti-interference capability, and large management capacity suitable for water, gas, and heat metering scenarios.
The document details the HAC-MLW module specifications, including its structure, interface definitions, technical parameters such as operating voltage (2.8V~6V) and dimensions (42.1mm*24.8mm*3.2mm), and usage methods like initialization and workflow. It also covers the HAC-GW-MLW gateway features, which supports up to 10,000 nodes with 8 LoRa receiving channels. This manual is written in Chinese.
| Communication Protocol | LoRaWAN 1.0.2 |
