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。
- 手机APP界面如下
连线
hx711安装焊接参考使用说明
hx711模块需要使用5v供电，注意vcc连线
功能实现
1.阿里云平台连接
阿里云环境创建参考高级组件库-aliyunIoT进行搭建。
创建产品，添加产品后添加物模型。

应用开发
以下是物联网应用开发流程，接下来按以下流程介绍移动端应用的开发。
3.1新建‘普通项目’
- 使用阿里云IoTStudio创建项目。
- 在项目管理新建空白项目
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
物体重量
单位"克"
系数k,最大值改2000
去皮
称重
再添加两个按钮用来切换模式
3.6保存预览
手机扫码就可以使用了
