If the potentiometer is kept at the maximum value, then the module is said to have low sensitivity.) At this stage the voltage at the non-inverting terminal is lesser than the voltage at the inverting terminal (assume that the voltage at the inverting terminal is greater than the GND potential), which leads the output of the LM393 to be a low value (0V).
