应用背景实现最基本的gprs 通讯功能，同时提供最低的能耗需求。 在此基础上，软件功能基于ucosII‐2.92 版本进行开发，软件提供demo 开源，硬件原 理图进行开源，软件未开源部分使用lib 库实现，提供lib 库，未开源部分为AT 指令 的流操作。关键技术由于目前物联网的推进以及GPRS 数据业务在各个行业的应用，该类似的设计产品在市 场上仍将占据一块很大的区域。同时现有的产品发展将面向客户以及模块化设计，单独设计 该款模块，用户只需设置很少的参数即可立即使用，同时模块将分别实现正常工作以及低功 耗工作两种模式。

应用背景The leading developers of Marlin are currently (January 2015) EvdZ and bkubicek, though many others contribute with their patches. This is a firmware for reprap single-processor electronics setups. It also works on the Ultimaker PCB. It supports printing from SD card+Folders, and look-ahead trajectory planning. This work is licensed under the GNU GPL v3 or (at the user"s discretion) any later version. It is based on Sprinter firmware, which was licensed under GPL v2 or later.关键技术 Features: Interrupt based movement with real linear acceleration. High steprate. Look ahead (Keep the speed high when possible. High cornering speed). Interrupt based temperature protection. preliminary sup

有两种方法来测量土壤水分：  1土壤水分张力和  2土壤含水量  土壤水分张力  土壤水分张力告诉你它是多么容易从土壤中抽取水。当土壤饱和时，有大量的水在孔隙空间和大量的水涂布土壤颗粒。 这一切的水分使得它很容易为植物根系获得水分和土壤水分张力低。  想象一下，吸吮冰泥泞 - 当你第一次启动啜，很容易喝一杯。你越喝就越难以从冰并获得液体更难，你必须吸 - 这是同为 植物根，水，在毛孔变小，吸力或紧张的根源需要申请获得水分增加。  当土壤张力达到一定的阈值时，工厂不能再从即使有水存在的土壤中提取的水，被卡住的土壤颗粒，他们不会让他走。这水
