Title RESEARCH ON SMALL INTELLIGENT WATERING DEVICE BASED MSP430
Abstract
In recent years,electronic technology as the representative of the new technology has promoted the rapid growth of the intelligent household equipment.Some family intelligent watering devices can only achieve time quantitative automatic watering,but can not achieve real-time monitoring and process control.Therefore, developing a small intelligent watering device according to humidity has become possible.
This paper reviews the background, purpose and significance of small intelligent watering device, described the structure and principles of the hardware in detail,completed detection circuit design based on capacitive humidity sensor to measure the humidit，which will be converted into electrical signals for transmission and measurement，completed drive circuit design based on relay,completed compilling and running of AD sampling procedures, conversion program,main program based on MSP430G2553.Finally it realized on-off control of watering according to judge the size of the Soil moisture and achieved smart watering results，which has some availability and can be applied to intelligent household equipment and automated greenhouse and other related fields.
Keywords：smart home;small intelligent watering device;MSP430
