AIM has designed these sensors to measure the tire's external temperature during track tests, necessary data for the perfect setup of the kart, as well as measuring the level of use of the wheels and the driving behavior of the driver. The sensors act in a range of temperatures ranging from -20 to 120 degrees, providing an output from 0 to 5V. The kit includes an infrared temperature controller necessary for connecting the MyChron5. Mounting brackets are also supplied.
