Overview
Zilog’s Passive Infrared (PIR) sensors are designed to deliver high performance and
excellent EMI immunity for the most demanding motion detection applications.
The ZBG323671 PIR sensor is used in combination with a PIR lens and consists of two
sensing elements behind a spectral filter window tuned to 8-13um wavelength to help block
out unwanted IR energy sources.

• Built in EMI compensation
• Elements are 1.0mm x 2.3mm spaced 1.0mm apart
• Standard metal TO-5 package
• Recommended operating voltage range of 3V to 10V
• Operating temperature range of -40C to +70C

Applications
• Security Motion Detector
• Video Doorbell
• IP Camera
• Wall mount lighting/HVAC Control
