IR Distance Sensing Module KY-032

My robot's been dodging obstacles all week and this little module hasn't missed a beat. The range adjustment screw is super handy for tweaking the detection distance without any code changes.

Finally got this module working with my Arduino robot and the adjustable range via the potentiometer made tuning it to avoid obstacles surprisingly easy. It reliably detects objects within the set distance without any false triggers, which is exactly what I needed.

The onboard potentiometer makes adjusting the detection range super easy — I dialed it to about 20cm for my robot and it's been spot-on. Solid little module for the price.
