I. Product Introduction

The WE-ST-S6 Farmland Water Quality Monitoring Station is a monitoring device used to observe the water quality environment in farmland. This equipment consists of water quality sensors, a data acquisition host, a power supply system, a communication module, an IoT cloud platform, and other components. It can automatically monitor water quality data such as dissolved oxygen, water temperature, pH level, water level, salinity, and ammonia nitrogen ions in paddy fields. The monitored data is transmitted wirelessly to the IoT cloud platform, providing users with accurate water quality data to support scientific decision-making and prevention measures.

It is primarily used in areas such as protecting water sources, preserving aquatic ecosystems, controlling water pollution, monitoring water environments, managing water resources, preventing water disasters, and supervising water environments.
