PIR Detector Miniaturized Module

•ꢀ Optional communication interfaces: I²C for

Network Mode or I/O for Stand�alone Mode

General Description

Holtek’s human body infrared detector micro mod�

ules, the HT7M21xx series, come fully integrated

with optical lenses, a passive infrared (PIR) sensor

and DSP algorithms. These modules include a wide

range of features such as low power consumption,

an I²C communication interface and DSP algorithms

which improve the reliability of the PIR detector.

Their application range includes home security and

surveillance system as well as basic industrial safety

detection.
