Hi Toby,
Thanks for your reply.
Could you be able to clear one thing for me?

Case: Consider that I am going to use one temperature sensor.To get the signal from this sensor If I wire/connect this with a USB-DAQ card ( i.e. LabJack-U3 is USB interface and its driver for Linux is already installed) and then want to write the driver for prayer;for which hardware I need to write driver for Player?
*For USB-DAQ Card or for the Temperature sensor or for both?

You dont give any details of the interface to your sensors. Player is purely
a software project, drivers can be written to interface to any existing
hardware that can interface to your PC (i.e. through a serial or USB port),
but it cant achieve magic, i.e.  reading pure analog values without an ADC.
Some of the drivers are already written (such as the URG laser (usb or
serial)), other more exotic devices such as fire detectors and so on will
probably need a plug in written to interface to, and if they do not already
have a serial interface they will also need some sort of intervening
hardware to read the device from the computer.
