ABSTRACT:The automatic watering system is designed based on the STC89C52 microcontroller. The system can achieve automatically watering the flowers at the time of the humidity changes, and be quantitative. Depending on the flowers of water required, a button is set to control the time of watering. Just need to open the watering pump when we need to watering the flower, otherwise close the pump. Depending on the humidity to control watering the flowers, there need a temperature and humidity sensor to detect the humidity and display the temperature and humidity data collected in the 1602 LCD. When the humility drops below the set humidity, the buzzer alarm and then the pumps began to water the flowers until reached the set humidity. The automatic watering system now can water the flowers automatically through experiments. The quantitative of water is tested by the software, and the water pump needs to work for 20 seconds. Firstly, the paper focuses on a single chip control system and the controlling of modular design and production. Secondly, the software also uses the modular design methods, including temperature and humidity detection module, controlling module, system turning module design, and programming by the keil 3 emulation software. The design implements a system by using the single chip microcontroller (SCM) to control smart watering and alarm functions. Specific hardware circuit and the corresponding procedures are designed.
