ZONEWU LoRaWAN Water Quality DO Sensor

Product Features:

LoRa water quality dissolved oxygen sensor is a device used to measure the concentration of dissolved oxygen in a solution. It adopts the principle of fluorescence measurement and does not require oxygen consumption or electrolyte. The sensor is equipped with a built-in temperature transmitter, which can achieve automatic temperature compensation. It is also equipped with imported quality fluorescent film, which has stable and reliable performance.
The sensor adopts imported grade fluorescent film, which has excellent stability and reliability; Relying on LoRa wireless transmission technology, it has a long communication distance.The LoRaWAN collector of this sensor is connected to the dissolved oxygen transmitter through an aviation connector, making it more convenient and efficient to use. Relying on LoRaTM spread spectrum modulation technology, its terminals can achieve ultra long distance communication and have been widely used in multiple industries such as water treatment, aquaculture, and environmental monitoring.

• Core Product Advantages

Compared with traditional polarographic devices, the mainstream fluorescence-based Water Quality DO Sensor has outstanding strengths: it delivers high detection accuracy, equipped with an intelligent compensation algorithm to control errors and ensure stable, drift-free data; it features a remarkable maintenance-free design, eliminating the need for electrolyte and electrode replacement, thus drastically cutting operation and maintenance costs; it possesses strong anti-interference and corrosion resistance, adapting to complex water environments such as turbid sewage and seawater; it also features low power consumption and easy installation, supports multiple communication modes, and is ideal for unattended and remote monitoring scenarios.

• Detailed Working Principle

This Water Quality DO Sensor adopts the fluorescence quenching optical detection principle, realizing accurate monitoring relying on optical physical properties: specific fluorescent materials emit fluorescence when irradiated by excitation light, and oxygen molecules shorten the fluorescence lifetime via quenching, with a strict negative correlation between oxygen concentration and fluorescence lifetime. The sensor excites fluorescence through an LED light source, the photoelectric module captures changes in fluorescence lifetime, and the dissolved oxygen concentration is calculated via built-in algorithms. The whole process involves no chemical reactions and consumes no oxygen in water, featuring fast response and no flow rate dependence, and the detection results are highly consistent with real water quality conditions.

• Core Application Purposes

This Water Quality DO Sensor enjoys a wide range of applications and acts as a key device for water quality control: it is used for surface water environment monitoring of rivers, lakes and reservoirs to support water ecological protection and pollution early warning; it is applied in sewage treatment plants to accurately regulate the aeration process, improve treatment efficiency and reduce energy consumption; it is suitable for aquaculture scenarios to monitor dissolved oxygen concentration in real time, link with oxygenation equipment to ensure the healthy growth of fish and shrimp, and realize refined aquaculture management; it can also be used for water quality monitoring in industrial wastewater treatment, scientific research experiments and other fields.
