I want to make a circuit that can convert the low, high, empty,overflow analog signals
from an ultrasonic pickup into digital signals eg 1 for True condition. I have never purchased such sensor form the market. The distance is maximum 20cm for empty level. It should be small in size. Please help with the possible design consideration, circuit, catalog website etc.
