使用实例以sensorTypeId为0的传感器为例,其他类型的传感器使用方式类似。
```
```c
#include "sensor_agent.h"
#include "sensor_agent_type.h"
#include "stdio.h"

1. 导入需要的包
```
#include "sensor_agent.h"
#include "sensor_agent_type.h"
```
```c
#include "sensor_agent.h"
#include "sensor_agent_type.h"
```
2. 创建传感器回调函数
```
void SensorDataCallbackImpl(SensorEvent *event)
{
if(event == NULL){
return;
```c
void SensorDataCallbackImpl(SensorEvent *event)
{
if(event == NULL){
return;
}
float *sensorData=(float *)event->data;
}
float *sensorData=(float *)event->data;
}
```

3. 获取设备支持sensor列表
```
SensorInfo *sensorInfo = (SensorInfo *)NULL;
int32_t count = 0;
int32_t ret = GetAllSensors(&sensorInfo, &count);
```
```c
SensorInfo *sensorInfo = (SensorInfo *)NULL;
int32_t count = 0;
int32_t ret = GetAllSensors(&sensorInfo, &count);
```
4. 创建的传感器用户
```
SensorUser sensorUser;
sensorUser.callback = SensorDataCallbackImpl; //成员变量callback指向创建的回调方法
```
```c
SensorUser sensorUser;
sensorUser.callback = SensorDataCallbackImpl; //成员变量callback指向创建的回调方法
```
5. 使能传感器
```
int32_t ret = ActivateSensor(0, &sensorUser);
```
```c
int32_t ret = ActivateSensor(0, &sensorUser);
```
6. 订阅传感器数据
```
int32_t ret = SubscribeSensor(0, &sensorUser);
```
> ![icon-note.gif](public_sys-resources/icon-note.gif) **说明:**
> 到这步就可以在实现的回调方法中获取到传感器数据。
```c
int32_t ret = SubscribeSensor(0, &sensorUser);
```
> ![icon-note.gif](public_sys-resources/icon-note.gif) **说明:**

7. 取消传感器数据订阅
```
int32_t ret = UnsubscribeSensor(0, &sensorUser);
```
```c
int32_t ret = UnsubscribeSensor(0, &sensorUser);
```
8. 去使能一个传感器
```
int32_t ret = DeactivateSensor(0, &sensorUser);
```
```c
int32_t ret = DeactivateSensor(0, &sensorUser);
```

5. 配置设备接口
```cpp
ret = g_usbClient.ClaimInterface(pip, interface, true);
interfacedeviceListdeviceinterface
ret = g_usbClient.ClaimInterface(pip, interface, true); //interface为deviceList中device的interface。
```
6. 数据传输
