Good sensitivity

The detection range is decent. Had to adjust the height from the ground slightly to get optimal readings. Good value.

Robust and reliable

Been using it for weeks on my smart car kit. No false positives so far. The LEDs help visualize detection status.

Instructions unclear

The module works well but the wiring diagram provided was a bit vague. Had to look up online tutorials. Product itself is fine.
