HT7M2126/27/36/56/76

PIR Detector Miniaturized Module

General Description

Holtek’s human body infrared detector micro mod�

micro mod�

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.

Features

• Operating voltage: 2.7V ~ 5.5V

• Operating temperature: �10 ~ 60°C

• Low power consumption:

♦

Operating mode (Moving objects to be detected)

< 1.5mA

♦

Standbywithdetectingmode<50μA(Operating

voltage 3.3V)

• Intelligent signal recognition algorithm

• Optional communication interfaces: I2C for

Network Mode or I/O for Stand�alone Mode

• Adjustable sensing sensitivity – Network Mode

• Customisable trigger modes: Single/Continuous –

Network Mode

• Adjustable trigger output time: 16�bit×100ms –

Network Mode

• Low voltage detection: 2.0/2.2/2.4/2.7/3.0/3.3/3.6/

4.0V options – Network Mode

• Supports external optical sensors (eg. photo

transistors)

• Integrated temperature sensor with temperature

compensation

• Quick stabilisation: ready for stable operation

within 12 seconds after power on

Applications

• Security Monitoring Systems
