PIR

Description

Unit PIR is a human body infrared Unit. It belongs to the “Passive Infrared (PIR) Detector” category, which works by detecting infrared radiation emitted or reflected by the human body or objects. When infrared is detected, it outputs a high level and maintains it for a certain period (allowing repeated triggers during this time) until the trigger signal disappears (returning to a low level).

This Unit communicates with the MC4.0 via PORT B.

*Note: There is a 2-second delay after detection.*
