Self Warning System for Danger Sense

The drone, after the increase of the flying area, must have a self system that detects the danger / particulates that may cause damage to the Drone.
For example, The element- Fire
The drone must have a heat sensor in addition to a resonated synchronized screen with the handler so that on exceeding a particular limit of the device or body temperature, it should beep or produce some sound to warn the user.
That will help the drone to stay intact for a longer duration plus will also not allow the enemy's plot to work and have a good time to escape the plot.
Hope that Helps :-)
