Description

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
