Nope, just one sensor for the Passenger side rear caliper (inner pad only). I have not done the front brakes yet, but on my old RRS there was one sensor in the rear, and one in the front. The sensors look to be the same design, just with different length harnesses.
No computer or anything is required to clear the message. When you turn on the ignition after replacing the pads/sensor, the brake pad warning will be clear. It will also clear from your Land Rover Remote App on your phone.
If I understand your last statement, you don't have the warning message yet, and you want to know if you need to replace the sensor? If that is correct:
I would have the sensor on-hand prior to changing the pads/rotors. The plastic of the sensor gets hard and brittle with the heat on the pad. I tried swapping a set of pads on another truck once and the sensor broke as soon as I started to pull it out of the pad.
If you have the warning already, the sensor has tripped (by wearing into the rotor), and must be replaced with the pads and/or rotors.
