SKU:U004












Unit PIR is a human body infrared Unit. It belongs to the "passive pyroelectric infrared detector" category, which operates by detecting infrared radiation emitted or reflected by a human body or object. When infrared radiation is detected, it outputs a high level signal and maintains it for a period of delay (remaining high level and allowing repeated triggering) until the triggering signal disappears (returns to low level).
This Unit communicates with the M5Core via PORT.B.
Note: There is a 2-second delay after detection is triggered.
