Working principle of dissolved oxygen probe Dissolved oxygen probe works by measuring the amount of oxygen that diffuses across a permeable (or semi-permeable) membrane into a dissolved oxygen sensor (probe). Once oxygen is inside the sensor, a chemical reduction reaction occurs, producing an electrical signal. This signal is read by the DO probe and is …
How does a UV sensor work? The circuit adopts the American imported industrial-grade microprocessor chip and imported high-precision ultraviolet transmitter to ensure the excellent reliability and high precision of the product. Features of uv sensor: 1. Adopt ultraviolet measuring devices that are highly sensitive to 240-370 nm to accurately measure ultraviolet intensity. 2. The see-through …
The role of rain and snow sensors The rain and snow sensor is a qualitative measuring device for measuring whether it rains or snows outdoors or in nature. It is equipped with imported intelligent microprocessors and advanced detection circuits. The surface adopts grid electrodes and uses the conductive characteristics of water. When there is rain or snow …
What are water quality sensors？ Water quality sensors can detect water quality in various applications. In particular, water quality monitoring systems can provide researchers, operators and engineers with critical water quality data for laboratory research, quality control, hydraulic model calibration, compliance and tracking of changes in water system quality over time. Sensors can be the …
How Water Quality Sensors Can Measure Water Quality Read More »
Introduction The electrochemical gas sensors contain two or three electrodes, occasionally four, in contact with an electrolyte. The electrodes are typically fabricated by fixing a high surface area precious metal on to the porous hydrophobic membrane. The working electrode contacts both the electrolyte and the ambient air to be monitored usually via a porous membrane. …
Where are co2 sensors required? Carbon monoxide sensor is widely used in offices, agricultural greenhouses, flower cultivation greenhouses, edible fungus sheds, industrial production and other places where carbon dioxide concentration needs to be monitored. With rapid economic development, people’s living standards have also improved significantly. Environmental issues have become the focus of the attention of various countries. …
What is smart farming? Smart farming is the application of Internet of Things technology to traditional agriculture, using sensors and software to control agricultural production through mobile or computer platforms, making traditional agriculture more “smart”. In addition to precise perception, control, and decision-making management, in a broad sense, smart farming also includes agricultural e-commerce, food traceability and anti-counterfeiting, agricultural …
What is a water quality PH sensor? A water quality pH sensor is one of the most essential tools that’s typically used for water measurements. This type of sensor is able to measure the amount of alkalinity and acidity in water and other solutions. When used correctly, pH sensors are able to ensure the safety …
Summarize： We all know that the chemical properties of ozone are extremely active. Its energy when it is free produces strong oxidation in an instant, which can sterilize, disinfect and detoxify. It is widely used in water plant sterilization and disinfection, tableware disinfection, indoor air purification, fruit, and vegetable preservation, there are also medical treatments, …
Soil nutrients are important： Soil nutrients are the basis for plant growth. Just like human beings eat, they obtain various nutrients for the body’s growth and development through the intake of meat and protein. Plants also need to absorb various nutrients from the soil. Among them, soil nitrogen, phosphorus, and potassium are the most important …
