本次项目中有一个植物管家功能节点，顾名思义，植物管家就是可以帮你自动照料植物花卉盆景，自动浇水（也可以手动控制浇水），随时掌控植物生长状态。先上实物图如下：

 

基于RSL10-002GEVB设计，扩展板板载了DHT22温湿度传感器、5V直流小水泵、AD接口电容式土壤湿度传感器、光敏电阻。系统框图如下：



光敏电阻用于感知光照，可扩展补光灯模块对植物进行补充光照，温湿度传感器用于感知周围环境温湿度，土壤湿度传感器用于测量土壤湿度，太干的话就自动浇水，小水泵则用于将水从储水瓶抽到花盆中。微信小程序目前提供土壤湿度值显示、光照值显示，水泵启停控制按钮。

 



 

本设计中，使用RSL10-002GEVB的2路ADC口A0、A1分别测量光敏电阻端电压值、土壤湿度传感器模拟输出，进而感知光照和土壤湿度，使用RSL10-002GEVB的DIO11作为控制小水泵启停，驱动电路原本设计使用继电器，但发现RSL10的IO驱动能力还是太弱，常用的继电器模块无法驱动，只好采用了十分简单的三极管扩流方法驱动5V直流小水泵。

RSL10-002GEVB端程序依旧基于peripheral_server例程实现，RSL10-002GEVB提供一个具有通知权限的特征值用于将采集的传感器数据发送给微信小程序，一个具有可写权限的特征值用于水泵控制。程序没什么新意，在调试驱动DHT22的时候，奈何总是失败，遂放弃，看来RSL10的IO还是需要深入研究才行。

将采集的两路AD数据用4个字节发送出去；接收到小程序发来的0x31则打开水泵，0x66则关闭水泵。

微信小程序逻辑十分简单，主要就是启动后加载页面，图标，收到蓝牙通知数据后触发回调进行数据显示，按钮按下后触发相应的回调函数并改变图标状态，发送数据给RSL10-002GEVB。

<pre>

<code class="language-javascript">// index.js
// 获取应用实例
const app = getApp()
var event = require('../../utils/event.js')

Page({
data: {
device_id:123,
device_status:"在线",// 显示是否在线的字符串，默认离线
plant_status:"良好",
checked: false,//led的状态。默认led关闭
shidu:0,//湿度值，默认为空
guangzhao:0,//光照值，默认为空
icon:"/utils/img/waterOff.png",//显示图标的状态，默认是关闭状态图标
},

//屏幕打开时执行的函数
onLoad: function () {
//接收别的页面传过来的数据
event.on('plantKeeperDataChanged', this, function(data) {
 //另外一个页面传过来的data是16进制字符串形式前面2个字节是A0端口采集的（光照）、后面2个字节是A1端口采集的（土壤湿度）
 console.log("接收到蓝牙设备发来的数据:"+data)

楼主的植物管家还行吧，很不错

RSL10的IO驱动确实不行，比较常用的继电器模块无法驱动是个小不足

&nb ...

是的，这个IO还是太少了，arduino接口上好几个空的
