Its hardware system includes signal amplifier circuit, A/D circuit, SCM, micro LCD display and alarm circuit, etc.; Software system includes A/D conversion driver, LCD driver two modules. Proteus software platform based on the design of the system is simulated, and the results show that the system hardware and software design correct and reliable operation.Keywords: soil humidity; Detector; SCM; A/D conversion; simulationTP202 classification number: ChineseLiterature identification code: ASection 1 IntroductionAgricultural production in the economic development of our country has important position, for farmers Industry production to provide timely and reliablly technical service has become the heavily meteorological department To response one. Along with the national governments at all levels of agricultural production increasingly heavierDepende on the service, my unit also serve for agriculture, promote for increasing farmers' incomeMany studies, the various problems in agricultural production also widely adjustableInquiry. Research found that gardening cultivation, greenhouse flowers, awning vegetables oneSome valuable varieties of soil moisture, soil has a high requirement, humidityAt the time, not only seriously affecting its normal growth, and even cause planting product death Wu, causing serious damage. Farmers Therefore, engaged in this kind of agricultural production.Farmers very need a low cost, small volume and detection reliable soil ....
