2. 持续监听传感器数据变化
2. 以下场景以加速度传感器ACCELEROMETER为例。展示持续监听传感器接口的调用结果
```js
import sensor from "@ohos.sensor";
sensor.on(sensor.SensorId.ACCELEROMETER, function(data){
console.info("Data obtained successfully. x: " + data.x + "y: " + data.y + "z: " + data.z);// 获取数据成功
console.info("Data obtained successfully. x: " + data.x + "y: " + data.y + "z: " + data.z); // 获取数据成功
});
```
以SensorId为ACCELEROMETER为例展示运行结果,持续监听传感器接口的结果如下图所示:
