Work content of small water quality monitoring station: Real time monitoring of key indicators of water bodies to grasp the current status and changing trends of water quality [Model: TW-LSZ03, IoT integrated device, Tianwei Environment supports customized services]In the practical scenario of dynamic monitoring of water environment, small-scale water quality monitoring stations have become the core tool for accurately grasping the health status of water bodies with high-frequency and multi parameter real-time monitoring capabilities. It continuously collects key indicators such as water temperature, dissolved oxygen, pH value, turbidity, chemical oxygen demand (COD), and ammonia nitrogen through sensor arrays deployed in rivers, sewage outlets, or pipeline nodes. It uses anti-interference design to ensure stable data transmission in complex water environments. After cloud analysis, these dynamic data can generate real-time snapshots of water quality status, revealing current pollution characteristics and ecological risks, and trace water quality trends through time series analysis - for example, identifying periodic fluctuations in industrial wastewater discharge or tracking the cumulative impact of agricultural non-point source pollution on downstream water bodies. Based on real-time monitoring and trend analysis, monitoring stations provide scientific basis for environmental management departments, supporting precise control of pollution sources, optimization of ecological restoration plans, and rational allocation of water resources, helping to build a full chain management system of "monitoring warning governance", and promoting continuous improvement of water environment quality.

1、 Product Introduction

The LSZ03 upright water quality online monitoring station uses water quality sensors (water temperature, conductivity, pH) as its core. By monitoring and analyzing various water quality parameters, and transmitting the collected data to the platform, real-time data can be remotely viewed and equipment can be remotely managed. At the same time, it can effectively alert and intelligently process water quality changes, and can also represent the comprehensive index of water quality based on the correlation between real-time water quality parameters. It provides customers with a large amount of objective and detailed effective data, which has practical significance for solving water pollution problems.

At present, the LSZ03 water quality monitoring station is widely used in aquaculture, sewage treatment, reservoirs, rivers and other places

2、 Product Features

1. Low power collector: static power consumption less than 1mA

2. Standard GPRS networking, support for extended Bluetooth, wired transmission

3. Support modbus485 sensor expansion

4. Solar charging management MPPT automatic power point tracking
