查看驱动上报值30左右，前端hap数值非常小，请教一下这个是什么原因呢？

前端代码：

//读取传感器返回值
  aboutToAppear() {
    this.callback = (data)=>{
      console.log('sensor.on receive: ' + JSON.stringify(data))
      let ppp = data
      this.sss =  "温度"+JSON.stringify(ppp)
    }
    this.callback1 = (value)=>{
      console.log('sensor.on receive: ' + JSON.stringify(value))
      let qqq = value
      this.zzz =  "湿度"+JSON.stringify(qqq)
    }

  }


  @Styles pressedStyles() {
    .backgroundColor(Color.Gray)
  }

  @Styles normalStyles() {
    .backgroundColor(Color.White)
  }

  build() {
    Column() {
      Column() {
        Text('温度数值')
          .margin({ top: 40 })
          .fontSize(20)
        Progress({ value: this.progress, type: ProgressType.Linear })
          .margin({ top: 10 })

        Text(this.sss)
          .fontSize(20)
        Text(this.zzz)
          .fontSize(20)

        Text('开始监听')
          .textAlign(TextAlign.Center)
          .fontSize(20)
          .margin({ top: 40 })
          .padding({ top: 12, bottom: 12 })
          .borderWidth(1)
          .stateStyles({
            pressed: this.pressedStyles,
            normal: this.normalStyles,
            clicked: this.pressedStyles
          })
          .width('100%')
          .onClick(() => {
//循环调用温湿度获取其值
                let timer: number = 0
                clearInterval(timer)
                this.timer = setInterval(() => {
                  try {
                    sensor.once(sensor.SensorType.SENSOR_TYPE_ID_AMBIENT_TEMPERATURE, this.callback);
                    sensor.once(sensor.SensorType.SENSOR_TYPE_ID_HUMIDITY ,this.callback1);
                  } catch (err) {
                    console.error('Once fail, errCode: ' + err.code + ' ,msg: ' + err.message);
                  }
                }, 1000)
          })
