The Design Of Solar-powered Detection Device In The Agricultural Greenhouse

Our country is one of the world biggest agricultural countries, due to the largepopulation base, per capita arable land area is little, so we still faces many problems andchallenges in agricultural development. Implementation and development of ecologicalagriculture in line with the national conditions is the only way to promote gooddevelopment of agriculture in China. This thesis is based on national conditions, and theeconomic and technical level have been fully taken into account the different types ofgreenhouse operators, researching and developing a intelligent monitoring device that ispractical, good market prospects, the price is cheaper, using solar-powered greenhouse.This device uses a high conversion efficiency of crystalline silicon solar panels forenergy conversion. Transformation of electrical energy stored in a longer life and nomemory lithium battery to provide electricity for the entire greenhouse environmentmonitoring device. The device mainly work is to real-time measure environment,temperature, humidity, light, and soil moisture of the greenhouse,which play an importantrole for the growth of vegetables, then store and display the collection of data. Asgreenhouses are widely used in artificial manipulation regulating environmentalparameters, the device is not designed control interface, but to use the display and alarmdevice to remind planting staff adjust the greenhouse environment in time. The device usesintegrated design, and there is no wires to connect with the outside world. The device alsoset the Bluetooth communicate port, and the vegetable cultivation process parameterscontrol database can be downloaded from the mobile computer (or smart phone).The lowerpart of device is designed as tapered probe rod, so it can arbitrary plugging in the soil. Weuse a high-speed, low-power STC12C5A60S2micro-controller as the core part in thecircuit. Sensors are selected lower costs, which have a certain level of integration,extensive application products. We chose the configured peripheral hardware and basicunderlying protocol IC Bluetooth module.The original intention of the design of the device is for economic and practice, and tofurther improve the accuracy and efficiency of the planting operations.The device is ableto run well at a lower cost in most rural greenhouse environmental conditions. After theexperiment, the sensor accuracy has basically reached the target. Through the trial,it canachieve greenhouse environment of the parameters of real-time data, accurate monitoring,acquisition and sending.
