HEART

创建传感器

const heart = hmSensor.createSensor(hmSensor.id.HEART)

heart 实例

heart: object

属性	说明	类型
last	最近一次心率测量值。设备心率自动监测会更新 last 值，注册 CURRENT 事件开启心率持续测量，也会更新 last 值	number
current	最近一次持续测量的测量值。注册 CURRENT 事件开启心率持续测量，会以一定频率，更新这个 current 值。如果在没有开启持续测量的情况下，获取 current 值没有意义	number
today	当日自 0 时起至当前时刻以分钟计的心率数据，返回 js 数组最长为 60*24	Array<number>

注册传感器实例回调事件

battery.addEventListener(event, callback: Callback)

CURRENT 事件

注册 CURRENT 事件后，会开启心率传感器进行持续测量，以一定频率，更新 current 值。

提示

持续监测心率，建议使用 CURRENT 事件

event 值

heart.event.CURRENT

Callback

() => void

事件示例

const hrCurrentListener = function () {
  console.log(heart.current)
}

heart.addEventListener(heart.event.CURRENT, hrCurrentListener)

LAST 事件

持续监听 last 值变化。

event 值

heart.event.LAST

Callback

() => void

事件示例

const hrLastListener = function () {
  console.log(heart.last)
}

heart.addEventListener(heart.event.LAST, hrLastListener)
