Description

A soil environment parameter collector with built-in cleaning function and its use method

Technical field

The invention relates to a soil environment parameter collecting instrument with a self-cleaning function and a method of using the same.

Background technique

With the development of modern agriculture, greenhouse cultivation technology has been widely promoted. There are a large number of small-scale greenhouses in our country. Farmers have relatively little professional knowledge about greenhouse cultivation and their management is relatively chaotic, resulting in low production efficiency. At present, most greenhouses still rely on manual farming and experience management, and do not use Internet of Things technology for scientific planting in greenhouses. The traditional model requires a lot of manpower, material and financial resources, and has low utilization rate of resources. It is not conducive to the development of future agriculture and can no longer meet the needs of the development speed of modern civilization. Research on modern agricultural equipment is urgent. With the rapid development of Internet information technology, the Internet of Things has been widely used in various industries. It is of far-reaching practical significance to apply Internet of Things technology to agricultural greenhouse cultivation and develop a stable and efficient monitoring system to achieve remote environmental parameter monitoring and switch control. In greenhouses, the key to reasonable irrigation technology is to irrigate with an appropriate amount of water at a timely manner to ensure that the soil and air humidity in the greenhouse can meet the needs of crops without causing excessive soil moisture content and excessive air humidity in the greenhouse. It causes anaerobic respiration of crops, causing root rot and mildew. Currently, water-saving irrigation systems on the market generally directly bury soil moisture sensors in the soil for a long time to collect data. Electrochemical reactions in the soil can easily cause corrosion and rust of the sensors, which greatly reduces the service life of the sensors.
