Hi Janardhan, AFAIK all sensors with uORB support can work with apps/testing/sensortest support.
I prefer to use simple char driver sensors to avoid overhead and make things simple, maybe Xiang can give your more help about your multi-application usage. Also you can take a look how it is done on the PX4 project, since uORB came from them.
