And I need to build up a series of iron sensor circuit to detect the cars that might stop at the traffic light juction. The microprocessor will then sensor-status from the sensor circuit and make its decision to run the traffic light.
So the sensor circuit logic level need to me at TTL logic level, so that it can link with my 8031 processor.

This consists of two coils: The first being monitored by a meter or comparator and the other inductively linked to the first coil, and used as the sensing loop.
The presence of a large quantity of iron above the sensing coil changes the flux linkage between the two coils and the difference can be detected as a voltage difference at the terminals of the first coil.
