山东理工大学 毕业设计 （外文翻译材料） 20年 6 月 The design Based on AT89S51 miniature soil humidity detector design Abstract: facilitate master soil moisture conditions, design the miniature soil humidity detector. 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; simulation TP202 classification number: Chinese Literature identification code: A Section 1 Introduction Agricultural 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 heavier Depende on the service, my unit also serve for agriculture, promote for increasing farmers income Many studies, the various problems in agricultural production also widely adjustable Inquiry. Research found that gardening cultivation, greenhouse flowers, awning vegetables one Some valuable varieties of soil moisture, soil has a high requirement, humidity At 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 .Soil humidity detector for water supply, provides the basis. In order to solve the above asked .Our problem, I unit combined with actual conditions of agricultural production, and the related units designed Home of high precision, to design the low cost of miniature soil moisture detection
