LoRaWAN-Enabled Dissolved Oxygen (DO) Sensor for Water Quality Monitoring

LoRaWAN-Enabled Dissolved Oxygen (DO) Sensor for Water Quality Monitoring

Xiamen ZoneWu  LoRa water quality dissolved oxygen sensor is a device used to measure the amount of dissolved oxygen in water. 

Xiamen ZoneWu LoRaWAN water quality Dissolved Oxygen sensor Features:

The DO sensor measures DO with a fluorimetric method that does not consume oxygen and does not use electrolytes.

Temperature-compensated transmitter is installed inside, which can automatically adjust the result of a measurement according to the water temperature to ensure the accuracy of the data.

Imported fluorescent film is used, the quality is good, and the measured data is stable and reliable.

The LoRaWAN collector and water quality dissolved oxygen transmitter are connected with aviation connectors, which are convenient and fast to install and disassemble.

It is based on LoRaTM spread spectrum modulation technology, and the signal can be transmitted far, so there is no need to worry about distance.

It can be very useful in water treatment, aquaculture, environmental monitoring and other industries.

Common knowledge of conductivity DO

What is the definition, expression and source of dissolved oxygen

Dissolved oxygen refers to the molecular oxygen dissolved in water, usually denoted as DO, expressed in milligrams of oxygen per liter of water and saturation percentage. The amount of dissolved oxygen generally comes from the supply of oxygen in the air or the oxygen produced by photosynthesis of plants in water.

How is dissolved oxygen in water consumed by reducing substances and biological activities

Dissolved oxygen is consumed by reducing substances such as sulfides, nitrite ions, and ferrous ions in water, as well as by the respiration of aquatic organisms and the oxidative decomposition of organic matter by aerobic microorganisms.

What factors affect dissolved oxygen saturation content and how do they affect it 

The saturation content of dissolved oxygen is closely related to the partial pressure of oxygen in the air, atmospheric pressure, water temperature, and water salinity. In freshwater, its dissolved oxygen is slightly higher than in seawater; The dissolved oxygen content decreases with the increase of water temperature; When the water temperature decreases, its dissolved oxygen content will increase; The lower the atmospheric pressure, the lower the amount of dissolved oxygen.

Why is dissolved oxygen called the capital of water body, and what is the relationship between it and the decomposition of organic pollutants 

Dissolved gas is the capital of water bodies and a basis for studying the self purification capacity of water. The decomposition of organic pollutants in water requires the consumption of oxygen, and the higher the dissolved oxygen, the stronger the ability of the water to decompose organic pollutants.

How do different dissolved oxygen levels affect fish respiration 

At 20 ° C and 100kPa, approximately 9mg/L of dissolved oxygen is present in pure water. When the dissolved oxygen level in water drops to 5mg/L, some fish experience difficulty breathing.

Application Scenarios

Aquaculture 

Monitor the calcium ion concentration of aquaculture bodies to ensure the health of aquaculture organisms and the stability of water quality. 

Seawater Monitoring

Monitoring the concentration of calcium ions in seawater is conducive to marine ecological research and the regulation of seawater aquaculture. 

Industrial Wastewater 

Monitoring the concentration of calcium ions in industrial wastewater helps with wastewater treatment and achieving compliance with discharge standards.
