0 描述 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 (...) 主要特色 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 (...) 0 Schematic/Block Diagram.pdf 470.18 KB , 下载次数: 1 物料清单.pdf 245.78 KB , 下载次数: 3 层图（或 PCB 布局）.pdf 2.87 MB , 下载次数: 1 TIDA-00213 Assembly Drawing.pdf 452.11 KB , 下载次数: 1 TIDA-00213 Fabrication Drawing.pdf 449.24 KB , 下载次数: 1
