Android项目源码基于传感器的温度计开发是android应用上的温度计，是通过传感器来感知外面的温度。应该说这个应用太强大了，用到传感器技术，并能时时更新。项目中代码层次分明，大部分方法都加了详细的注释。对于想学习传感器的开发人员来说，简直是福音。（项目采用GBK编码，是studio工程）。(Android project source sensor based on the development of the thermometer is a thermometer on the Android application, it is through the sensor to sense the temperature outside. It should be said that this application is too powerful, the use of sensor technology, and can always update. Items in the code level, most of the methods have added a detailed notes. For developers who want to learn sensor, it is the gospel. (the project uses the GBK code, is the studio project).)
