综合案例2.0 - 称重数据上传云端

案例说明
连线
功能实现
- 1.阿里云平台连接
代码
- 应用开发
- - 3.1新建‘普通项目’
  - 3.2关联产品和设备
  - 3.3新建‘移动应用’
  - 3.4添加组件
  - 3.5配置组件信息
  - 3.6保存预览

案例说明

使用hx711串口模块称重,结合IOT studio制作手机APP远程控制并采集物体重量。

hx711串口模块用多种使用模式，这里只使用方式1，指令0xA1。
使用流程
- 手机APP界面如下
- 1，用于显示物体重量
- 2，用于矫正称重的精准度物体重量计算公式：实际重量=传感器数据/K； // K 是一个系数，通过调节K值调节称的精准度。
- 3，去皮是去掉装物品的篮子之类的容器的重量，可以准确称出称量物的实际重量。先按去皮按钮，重量显示为零，再把要秤的物品放进容器里，显示的就是物品的实际重量了。
- 4，称重，在模式1下，每次按下称重才会将当前物体的重量显示在APP或OLED屏幕上.
- 5，进行模式切换，模式一的情况下每次按下称重才会显示当前重量。模式二的情况下当称上物体重量发生变化就会显示数据，每秒显示一次。

'''
A通道采集数据增益128倍,精度更高.B通道增益只有32倍
波特率9600bps,无校验位,停止位1,返回数据10字节.
串口模块只需发送对应指令即可控制HX711.
工作方式1只读取数据,需要自己计算重量
工作方式2需要校准,调整系数k
案例使用工作方式1,
