What is your target made of? What is the angle of the target in relation to the sensor?

Surface angle and material both have a big impact on the maximum range, to get maximum range you need a large hard flat surface that is at 90 degrees to the sensor.

The target is the floor which is made up of tiles and i kept the sensor at 90 degrees to the floor but the reading i am getting after a certain range is only around 50-60
