A. The output from the ranging module is an open collector TTL compatible signal, going from low to high when an echo is received. To get distance information out of the module, the user measures the elapse time between when the module transmits until the echo is received. Knowing the speed of sound in air, (343.2 m/sec), this time measurement can be converted into distance. There is no analog signal output from the module.
