Thermopile-Based Occupancy Detector for People Counting Applications Reference Design
Texas Instruments
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
Applications
- Washers & Dryers
- Refrigerators & Freezers
- Cooking Ranges
