Too Sensitive
The sensor is very sensitive, maybe too much for my specific application. It took a lot of tweaking to get it right. Works fine if you need high sensitivity.

Perfect for Arduino Projects
This sensor module works exactly as described. I used it for a security box alarm and the sensitivity is easy to adjust with the potentiometer. Highly recommended for beginners.

Good Sensitivity
Works well overall. Had to spend some time calibrating the sensitivity to avoid false positives, but once set up it is very reliable. Good value for the price.
