The Design And Realization Of The Household Flower Intelligent Irrigation System

With the development of society,people’s pursuit of the quality of life is becoming more and more intense.As more and more buildings are built in cities,but the construction of green belts is neglected,resulting in less and less green areas and less opportunities for urban people to get close to nature.Every day,people in downtown areas have a strong feeling of being close to nature from the bottom of their hearts.People yearn for a comfortable and peaceful green life.Planting potted plants can purify carbon dioxide,absorb harmful gases,make indoor air more fresh,and also make people feel more comfortable.In recent years,potted intelligent watering has become a new topic of discussion.For example,in daily life,people are always busy with work or travel,so they have no time to consider potted watering work.According to the survey,as a result of watering problems caused by the growth of flowers and plants up to 80% of the problems.In order to solve the problem of potted irrigation,an intelligent flower irrigation system based on STC89C52 and ADC 0832 is designed in this paper.The main contents of the design include hardware circuit design and software design.Hardware design includes the design and fabrication of floor circuit,soil moisture detection,temperature detection,fan control,intelligent irrigation and alarm module.Software design includes pin assignment of STC89C52,sensor software design and clock parameter setting.The working principle of this circuit is that the soil temperature and humidity sensor detects the humidity in potted plants and sends the collected data to the IN terminal of ADC0832 as the input analog signal.When the soil humidity sensor and the A D conversion are selected,the A/D converter is activated by issuing instructions.ADC0832 selects the IN1 channel according to the address signal sent,and then converts the input analog signal.At the end of the exchange,EOC output high level.When MCU needs to collect data,at last,the humidity data collected by MCU is processed by software program and sent to LCD1602 for display [3].Intelligent potted irrigation system is to set potted temperature and humidity threshold through single chip computer programming.If the sensor detects that the potted humidity is lower than the threshold,it automatically opens the pump to irrigate it.When the soil humidity exceeds the threshold,the single chip computer will output a signal to make the pump stop irrigation automatically.In a real sense,we should "go out on business,flowers and plants have no worries".Based on STC89C52 single-chip computer,the intelligent control irrigation system of family flowers aims at improving the quality of water and saving water resources in intelligent watering.Through real-time analysis of soil moisture in plant roots,combined with various data indicators in the system,the watering process is controlled to achieve precise control.
