First check sensor without controller. Connect power supply and keep an object near the sensor. Measure output voltage. Keep moving object and notice variations in output voltage..!!
First make a table of Ditance vs output voltage for accurcate system.
Keep that table here and we will tell what to do next..!!
all the best
