1. Product Introduction

Primarily used for the collection, storage, processing, and transmission of hydrological rainfall data. Defaults to the SL651-2014 message format, but can be customized according to customer requirements. The intelligent rainfall sensor employs an embedded hardware architecture, supports parameter configuration and remote firmware upgrades via mobile app, and integrates solar panels, lithium batteries, control modules, and communication modules, optimizing the construction and maintenance of rainfall stations.
