Dissolved Oxygen Sensor MW-O101
Summary:
It is widely used in ORP value detection in the fields of laboratory scientific research, water supply, wastewater treatment, aquaculture, farmland irrigation, etc. The MW-O101 sensor is a polarographic dissolved oxygen sensor. Under a certain polarization potential of the sensor, the oxygen dissolved in the water body will pass through the oxygen permeable membrane, and a redox reaction will occur on the surface of the working electrode, and the resulting current is proportional to the concentration of dissolved oxygen in the water body. The concentration of dissolved oxygen in water is estimated by measuring the magnitude of the current.
Feature:
* High sensitivity, low power consumption
* Excellent stability
* Temperature Compensated, Excellent Linear Output
* Provide serial port (UART), PWM waveform and other output methods
* Long lifespan
* Anti-water vapor interference, no poisoning

APPLICATION
As we all know, there are a lot of pollutants in swimming pool water, and the polluted water can easily become a source of transmission of some diseases, causing various discomforts to swimmers. Therefore, the use of online water quality monitoring equipment for real-time monitoring and strict filtration and disinfection of pool water is an important link to prevent the spread of various diseases, protect swimmers and improve the quality of pool water.
Whether it is fish, mussels or other aquatic organisms, there must be an suitable environment for their growth in order to achieve a good harvest. The environmental conditions of water are one of the important reasons that affect the yield of aquatic products. With the acceleration of the construction of the Internet of Things, the intelligence of aquaculture has also become a development trend of large-scale aquaculture in the future.
