An IR coded signal is transmitted at the rear of a moving
car. At the same time an IR input is checked for the
same coded signal as just sent out. If the same signal
is found, then there is a car in the driver’s blind spot and
an LED is illuminated near the mirror. This system
would need to be implemented on both sides of the car.
The transmitter and receiver section need to be
shielded from each other.
