Which brand of watering artifact is good

1. The brands of good watering artifacts are: Nedest, which has super jet power, which can make watering easier. Jayden is made of stainless steel, which is very durable and easy to clean. Green Art State, high pressure, very light, with long-lasting endurance.

2. The good brands of vegetable watering artifacts are: Nedest: The brand of vegetable watering artifacts have some unique characteristics and advantages, such as super strong jet force, which can make watering easier.In addition, the vegetable-watering artifact of the Nedster brand also has the advantages of high efficiency, effort-saving and water-saving, which can meet the needs of different users.

3. Hello, Senniu. Senniu is one of the cost-effective charging water pump brands for watering vegetables. Its 3-inch four-stroke pumping pump has the characteristics of high-pressure and high-lift agricultural irrigation machine, self-priming fish pond pump, fire-fighting agricultural, mechanical and electrical hardware tools, etc. The quality is very good, the price is very affordable, and it is deeply loved by users. That is, the water pump for watering vegetables is good.

4. Silver Dragon Island Silver Dragon Island in Germany is an agricultural multi-functional rechargeable lithium battery electric sprayer. It has the functions of high-pressure pump and large-scale operation, which can easily spray pesticides, disinfect and kill them. Its nozzle can adjust the high-pressure water pump, making the operation easier.

Inadequages of Intelligent Watering System

1. Water cannot directly reach the roots of plants. If it is completely penetrated, it is difficult to control the amount of watering, and the close combination of different functional modules fails to achieve the expected effect of meeting the watering needs of different plants. A plant equipped with a watering device is inevitably cumbersome and a waste of resources.

2. The most obvious disadvantage is the battery life. After Huawei's many brands of mobile phones are upgraded from the Android system to the Hongmeng system, the mobile phone is hot, and the battery life is greatly reduced, which is very unfriendly to young people who are deeply dependent on mobile phones.

3. The current problems of intelligent irrigation systems are difficult to promote. The existing agricultural intelligent irrigation system has invested a large amount, and most farmers still have a wait-and-see attitude towards intelligent irrigation technology based on lack of understanding, economic perspective and risk considerations.

4. There is no need to take water, resulting in a waste of water resources and a serious shortage of groundwater. The well house is old, and the installation method occupies a large area of arable land. The machine well is exposed, and there are safety hazards.

How does a single-chip microcomputer design an automatic watering controller? Do you want to water the flowers in the morning and evening according to the humidity?

The soil humidity sensing solar automatic watering device of the patented technology of this invention includes a water tank, an inlet pipe, an injection pipe, an outlet pipe, a first soil humidity sensor, a second soil humidity sensor and a control box.

If it is time to water the flowers, then start the water pump to water the flowers with a certain amount of water. The amount of water can be determined by several experiments, and then timed by a single-chip microcomputer to determine how many seconds the water pump is turned on. It can also be calculated by the flow rate of the pump and the humidity of the flower soil. Then make sure how many seconds the water pump is on.

LCD1602 liquid crystal display, the upper line shows the current date and week, and the lower line shows the hour, minute, second and switch status.DS1302 clock chip, accurate timing, no need to re-adjust the time when the power is lost. The time of closing and disconnecting the relay can be set by pressing the button, and the relay is externally connected to the water pump, so as to achieve the effect of intelligent watering.
