Abstract
Automatic water-saving irrigation techniques represent the level of development of the modernization of agriculture, irrigation systems, low level of automation is constraining the development of China's main reason for high-efficiency agriculture. This article studied this issue MCU drip of water-saving irrigation system, which can be of different soil moisture monitoring, and in accordance with the crops on soil moisture requirements of timely and adequate irrigation, constitute the core of which is single-chip control some, mainly on soil moisture and the relationship between irrigation, irrigation control technology and equipment, system hardware, software, programming the various parts of an in-depth research.
SCM Singlechip optional part of the hardware part of STC12C2052AD as the core, mainly by soil moisture sensors, display circuit, the output control circuit, such as composition, choice of C language programming software. System has the following functions can be provided in single-chip control buttons to set the requirements of soil moisture, crop-related parameters; Singlechip soil moisture sensor can be detected in the soil moisture analog to digital volume, shown in the digital tube, the At the same time, this humidity value of single-chip chip set humidity values, when collected humidity Humidity is lower than the set value, the part of the implementation of control circuit for irrigation; when collected humidity humidity values higher than the set value, the control circuit to stop the implementation of parts of irrigation.
The system is flexible, easy-to-use, high reliability, there will be a broader development prospects.
