We can not say why this module is called 'Flying Fish' - but the IR infrared obstacle- and distance-sensor is perfect for recognizing objects in an angle of 35° and a distance between 2 and 30 cm. The principle is simple - an infrared LED light up and the photodiode next to it measures the reflection, thereby the module can calculate the distance.
With the potentiometer you can adjust the distance until the triggering: clockwise for increase, counter clockwise for decrease. 2 LEDs of the module signal to you, whether it is turned on and if it reach the chosen distance.
