摘要
随着信息技术的高速发展,智能手机已成为人们不可缺少的随身设备;为了使手机用户可随时感知周围环境参数,文章提出了一种基于智能手机音频接口的便携式环境感知系统;采用Quick-Jack通用平台将传感器模块连接到智能手机,通过APP应用程序可随时感知温度、湿度、空气质量等环境状况;系统功耗低至8.9mW,可直接从音频接口采集电能,无需外部供电和无线配对,成本较低,可靠性高,使用便捷。
With the rapid development of information technology,smart phones have already become an indispensable part of people＇s life.In this paper,we present an environment system based on audio jack of smart phones.Through Quick-Jack platform,the system can connect the sensor device to smart phones through the audio jack to collect sensor data.This system uses APP for human-computer interaction to display condition of the surrounding environment.It is cost-effective about 8.9mW lower energy cost without external power supply and wireless pairing which also can plug and play and easy to use.
