Thermopile-Based Occupancy Detector for People Counting Applications Reference Design

The Thermopile Based Occupancy Detector is a subsystem solution that uses a thermopile array to sense the body heat of people within its field of view and estimate the number of people present. This system requires less signal processing complexity than a video system to estimate the number of people present and uses less power.

Features:

-Thermopile array senses area occupants’ body heat
-System estimates the number of people it sees by counting heat signatures
-Low Noise, Low Power Analog Front End with 16 bit ADC and SPI Interface, uses only 221µA during operation
-Uses less than 190 mW during operation
-This circuit design is tested and includes firmware, design data and a detailed User Guide
