Review on Oiyagai 2Pcs SR602 Motion Sensor Detector Module Pyroelectric Infrared Sensory Switch by Adam Quintana
You are not accurate enough.
Even after many adjustments, three out of five can miss the person walking directly in front of them half the time. I haven't tested the other two and intend to desolder the PIR sensor and build my own circuit instead.
- The high level output time is adjustable from 2.5 seconds to 1 hour, and the factory output time is 2.5 seconds. The blocking time is not adjustable.
- There are other interesting options.
