Internet of Things technology is also widely used in greenhouses.
Greenhouses are mostly used in seasons where plants are not suitable for growth. They can provide growth periods and increase yields. They are mostly used for the cultivation of low-temperature seasonal vegetables, flowers, forests, and other planting or nursery. Therefore, the requirements for the growing environment of planting crops must be more precise. Most farmers rely on the feeling of warming, watering, and ventilating the greenhouse. When people feel cold, they warm up. When they feel dry, they water and feel bored and ventilated. There is no scientific basis. After agriculture entered the age of information, more and more attention was paid to the collection of agricultural environmental information such as air temperature and humidity, soil temperature and humidity, CO2 concentration, and light in the greenhouse. Therefore, the Internet of Things technology will be introduced into greenhouses.
In a greenhouse environment, a single greenhouse can become a measurement and control area for a wireless sensor network. With regard to the current situation of many factors that can be regulated in a greenhouse, high economic value added, and low level of automated information, we can use the Internet of Things technology to use different sensors. Nodes and nodes with simple actuators (fans, low-voltage motors, valves and other actuators with low operating currents) form a wireless network to measure soil moisture, soil composition, pH, precipitation, temperature, air humidity and pressure, and light intensity , CO2 concentration to obtain the best conditions for crop growth, through model analysis, automatic regulation of the greenhouse environment, control of irrigation and fertilization operations, while issuing warning information to achieve greenhouse intensive, networked remote management. Application of Internet of Things technology can achieve the purpose of increasing crop yield, improving quality, adjusting growth cycle, and increasing economic efficiency.
