Four parameter water quality monitoring system

　　Four parameter water quality monitoring systemFocusing on temperature, conductivity pH、 The four key indicators of dissolved oxygen comprehensively present the basic characteristics of water quality. The temperature sensor sensitively captures changes in water temperature, which affects the metabolism and distribution of aquatic organisms. Conductivity sensors reflect the content of dissolved substances in water by measuring current conductivity. The pH sensor accurately measures the acidity and alkalinity of water bodies, which is related to the living environment of aquatic organisms. Dissolved oxygen sensors monitor real-time oxygen concentration in water to ensure the respiratory needs of aquatic organisms. The system has a compact structure and stable performance, and is widely used in various water bodies such as rivers, lakes, and drinking water sources, providing accurate data support for water quality monitoring, water resource management, and protection.

1Four parameter water quality monitoring systemProduct Overview

The low-power collection microsystem of the pipeline network directly transmits JSON data to the designated server through 4G and supports MQTT protocol transmission.

Other formats of data are transmitted to our company's cloud platform via 4G. Our company provides an HTTP interface, and other platforms obtain data through this interface.

The built-in 8GB TF card can store the read data in the memory card.

The baud rate of each serial port communication can be modified through commands, and the required sensor parameters can also be added, modified, and deleted through commands.

2、 Functional Features

1. Equipped with a built-in 3.6V 152AH lithium battery, ensuring continuous operation for 3 years.
