[md]## 如何读取运动传感器比如加速度传感器

**第一步声明权限**

```
{
  "name": "ohos.permission.ACCELEROMETER"
},
```

**第二步导入sensor (传感器)模块：**

```
import { sensor } from '@kit.SensorServiceKit';
```

**第三步设置加速度传感器数据回调监听：**

```
try {
sensor.on(sensor.SensorId.ACCELEROMETER, (data) => {
console.info('X-coordinate component: ' + data.x);
console.info('Y-coordinate component: ' + data.y);
console.info('Z-coordinate component: ' + data.z);
   }, { interval: 10000000 });
} catch (err) {
console.error('On fail, errCode: ' + err.code + ' ,msg: ' + err.message);
}
```

## 完整代码

```
import { sensor } from '@kit.SensorServiceKit';

@Entry
@Component
struct SensorPage {
@State message: string = '加速度';

build() {
Column() {
Text(this.message)

   .fontSize(50)
   .fontWeight(FontWeight.Bold).onClick(() => {

try {
sensor.on(sensor.SensorId.ACCELEROMETER, (data) => {

this.message = JSON.stringify(data)

console.info('X-coordinate component: ' + data.x);
console.info('Y-coordinate component: ' + data.y);
console.info('Z-coordinate component: ' + data.z);
   }, { interval: 10000000 });
   } catch (err) {
console.error('On fail, errCode: ' + err.code + ' ,msg: ' + err.message);
   }

   })
   }
   .height('100%').justifyContent(FlexAlign.Center)
   .width('100%')
  }
}
```

**完毕。**
