PIR Motion Sensor |

A PIR Sensor can tell when something nearby moves. The sensor detects the pattern of infrared energy in its surroundings. If the pattern changes, the sensor outputs a high signal. The Propeller microcontroller only needs to monitor this signal with an I/O pin to know if something is moving around nearby.

PIR Sensor behavior with ambient lighting changes ...

2016-12-03· I have the PIR sensor Rev. B 555-28027: I understand from the information sheet that it takes 40 seconds upon startup to determine a baseline reading on the IR flux into the sensor, then uses that to determine a significant change to indicate motion. I have a few questions: 1. What happens if the ambient lighting condition changes, slowly, or rapidly to a new overall level? 2. Is a new ...

Advanced Motion Detector Using PIR Sensors Reference ...

Motion detectors containing one PIR sensor, a Fresnel lens with a cone-type beam, and a binary output are very efficient for detecting any type of motion, including a human or pet. However, imagine a customer application based on this type of motion detector that sends a notification and switches on a light when any motion is detected. It could be very annoying to receive notifications and on ...

PIR Motion Sensor |

— A faint red glow from two LEDS inside the PIR Sensor Rev B’s white dome indicates that the sensor is triggered. It is typical for the sensor to be triggered when it is first powered up and getting an infrared reading from its environment. Once triggered by start-up, or by a moving object, the sensor stays in that state and sends a high signal for several seconds. Passive Infra-Red ...

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 …
