7. Head Sensors
The sensors are optical devices that receive the infrared signal and
convert it to an electrical signal suitable for the PCB to work with.
The sensors have a big impact on the range that the system can work at.
They incorporate bright "hit leds"; LEDs that flash when hit
to confirm to the other players when they have hit you.
They connect to the gun using a "curly cord"; a black highly
flexible cable that is very durable.
