目前,健身手环在人们的日常生活中变得越来越流行,它不仅可以计算人行走的步数,而且还可以记录您燃烧的卡路里、显示心跳、显示时间等等。通常这些物联网设备已与云平台连接同步,因此您可以在智能手机上轻松获取所有身体活动量的历史记录。在前面的文章中,我们还制作了一个基于物联网的患者监护系统,其重要数据发送到ThingSpeak云平台,用户可以从任何地方进行查看。 计步器(Pedometer)是一种用来计算人走路步数的设备。在本篇文章中,我们将使用Arduino开发板和加速度计ADXL335制作一个简单又便宜的计步器。该计步器计算走路步数,然后将计算结果显示在LCD1602显示屏上。 所需的组件 ● Arduino Nano开发板 ● ADXL335加速度计 ● LCD1602液晶显示屏模块 ● 电池 ADXL335加速度计介绍 ADXL335是一款小尺寸、完整的三轴加速度计,基于电容式感应原理。它是一个小尺寸、薄型、低功耗的模块,带有一个经过多晶硅表面微机械加工的传感器和信号调理电路。 ADXL335加速度计可以测量静态和动态加速度。在本文中,ADXL335加速度计用作计步器传感器。 加速度计是一种可以将任意方向上的加速度转换为其相应的可变电压的设备。该设备通过使用电容器来实现的,随着加速度移动,位于其内部的电容器也将根据该运动而发生变化,由于电容是变化的,因此可以获得可变电压。

问题 I know already tizen pedometer step count of day can get from "tizen.humanactivitymonitor" in case of web application. but I fail to get it in web app on real gear s2 device. And also I try it with Native System sensor API. but I can not found the Pedometer API in Tizen Native API. How can I get Step Count of Day in both of Native and Web side? 回答1: Using the Tizen Wearable SDK 2.3.2, there is no way to read the S Health step count data. These are your options: WebAPI + Samsung Digital Health

问题 I try to put this plugin on my Android app https://github.com/leecrossley/cordova-plugin-pedometer I put this on my OnDeviceReady : var successHandler = function (pedometerData) { alert(pedometerData.numberOfSteps); }; pedometer.startPedometerUpdates(successHandler, onError); I tried several code but it doesnt work, Someone has a solution please 回答1: check that plugin is properly installed with : cordova plugin list If you do not see it in the list, run: cordova plugin add cordova-plugin

CMPedometer queryPedometerData() returning 0 steps when steps exist

问题 There seems to be a bug in the CMPedometer queryPedometerData() method. The method is returning 0 steps for certain end times, but the same query with the timestamp 1 second higher or lower returns the correct number of steps e.g. self.getStepsBetweenDates(NSDate(timeIntervalSince1970: 1543392126) as Date, date2: NSDate(timeIntervalSince1970: 1543393044) as Date) returns (Int) 1488 self.getStepsBetweenDates(NSDate(timeIntervalSince1970: 1543392126) as Date, date2: NSDate(timeIntervalSince1970
