CALORIE

创建传感器

const calorie = hmSensor.createSensor(hmSensor.id.CALORIE)

calorie 实例

calorie: object

属性	说明	类型
current	当前消耗卡路里，单位 kcal	number
target	目标消耗卡路里，单位 kcal	number

注册传感器实例回调事件

calorie.addEventListener(event, callback: Callback)

CHANGE 事件

event 值

hmSensor.event.CHANGE

Callback

() => void
