MODBUS is an international standard communication protocol for exchanging data between devices of different manufacturers (generally for industrial use); the so-called protocol, which can also be understood as the "language" someone said above, is simply software.

MODBUS was invented by MODICON (now a brand of Schneider Electric) in 1979 and was the world's first true bus protocol for industrial sites.

Soil is the root of flower growth. Soil can store rich nutrients and microorganisms for a long time, and it can continuously supply the growth and development of flowers and trees, and it also plays the role of fixing the plants. There are many types of soil, and its structure, texture, fertility, pH and other factors directly affect the growth of flowers. Therefore, if you choose to use a soil meter to test the soil, it will be more beneficial to the survival of flowers.

The texture of soil is generally divided into sandy soil, clay and loam.

In the medical field, various medical auxiliary devices are indispensable as auxiliary tools for medical diagnosis and treatment. For example, virus test kits, blood test kits, rapid microbiological test tools and immersion slides are various test tools used to monitor the sanitation level of various institutions. These auxiliary diagnostic devices need to be stored in a medical refrigerated cabinet, and they have high requirements for the temperature and humidity range, and must be in the specified storage range and conditions.
