How can I transmit live data from a drone to my laptop?I would like to transmit sensor data(say pollution sensor) from a drone to the ground station.What boards can help me do that?

I've seen it done, but it seemed to be more than just software for the computer; you need some sophisticated parts on the drone too. Those drones cost $1000+ as far as I know...
Try a more specific Q&A site. Just google variations on your question, 'transmit from drone to computer.'

Signals from a drone to a PC are transmitted usually through WiFi. But you will also need specialized software that will read and translate the signals.
