Faulty PIR Sensor? — Parallax Forums

2012-04-06· I recently bought a PIR Rev B motion sensor for a very simple project. The goal is to hook this motion sensor up to a buzzer that sounds when the PIR detects motion. I'm not using any microcontroller for this -- I'm simply connecting the output of the PIR to the buzzer. However, the PIR never seems to "warm-up", no matter how much time is given. It remains stuck on, and occasionally …
