#RT_Thread 软件包和组件包
##实践：采集温湿度上传MQTT平台
###软件包：
打开温湿度传感器：
在命令行输入menuconfig进入以下步骤，保存后退出输入pkgs -update即可下载代码

###代码测试：
串口展示温湿度示例：将下面代码烧录进板子，打开串口可以看到数据
```c
#include <board.h>
#include <rtthread.h>
#include <drv_gpio.h>
#include <aht10.h>

#define AHT10_I2C_BUS "i2c3"

#define THREAD_PRIORITY 25
#define THREAD_STACK_SIZE 2048
#define THREAD_TIMESLICE 5

rt_thread_t AHT10 = RT_NULL;

void AHT10_Test(void)
{
    aht10_device_t Dev = RT_NULL;

float Humi,Temp;

Dev = aht10_init(AHT10_I2C_BUS);
    if(Dev == RT_NULL)
    {
        rt_kprintf("AHT10_init Fail");
        return;
    }

while(1)
    {
        Humi = aht10_read_humidity(Dev);
        Temp = aht10_read_temperature(Dev);

rt_kprintf("Humi: %d.%d\n", (int)Humi, (int)(Humi * 10) % 10);
        rt_kprintf("Temp: %d.%d\n", (int)Temp, (int)(Temp * 10) % 10);

rt_thread_mdelay(1000);

}
}

void AHT10_Creat_Thread(void)
{
    AHT10 = rt_thread_create("AHT10",AHT10_Test,RT_NULL,THREAD_STACK_SIZE,THREAD_PRIORITY,THREAD_TIMESLICE);
    
    if(AHT10 != RT_NULL)
    {
        rt_thread_startup(AHT10);
    }
    else
    {
        rt_kprintf("AHT10_Thread Create Fail");
    }
}

MSH_CMD_EXPORT(AHT10_Creat_Thread,This Function will creat a AHT10 thread);

int main(void)
{
    return 0;
}
```
