商品說明

24GHz Human Stationary Presence Sensor 毫米波人體靜止存在雷達感測器模組是一款基於英飛凌毫米波 FMCW 工業雷達的獨立模組近距離感測器，工作頻率為 24GHz。該單元採用增強型多普勒雷達信號處理機制和標準算法構建，能夠區分佔用和非佔用條件，並在自適應環境中識別人類活動。它是智能家居、人體行為檢測、危險警報等個別應用中高精度、自我調節、隱私保護、安全的生物雷達系統的理想解決方案。

與傳統的 PIR 感測器相比，人體靜止存在模組對站立、移動和跌倒等人體活動具有更高的靈敏度。而且由於發射波是毫米級的，即使是遮蔽物，它也將保持功能。與 PIR 傳感器的短響應不同，該模組會持續不斷地感知人，這使得它在客廳、酒店甚至監獄中都非常有用。

該模組包含一個標準的自學習算法，它可以同時檢測，保護隱私，它可以管理不同的環境，無論位置是有點嘈雜還是非常安靜。在此之上，它大大降低了非生命物體的干擾，檢測輸出精度高達95%。

模組上內置雙陣列高性能天線，具有扇形波束模式波束寬度，水平為 90°，垂直為 60°，使其感應面積高達 96 平方米。此外，它甚至可以感知微動。該模組對環境的適應性很強，即使環境因素不同，也能保持正常運行。輸出功率非常低，即使長時間暴露也不會對人體造成傷害。

該單元支持二次開發，體積小、數字輸出、內部算法等可改進因素，通過Wio Terminal或XIAO系列等開發板使用UART通信接口可應用於多種場景應用。

Description

The mmWave Human stationary Presence Radar Sensor Module is a self-contained module near distance sensor based on Infineon mmWave FMCW industrial radar operating at 24GHz. The unit is built with the enhanced Doppler radar signal processing mechanism and standard algorithm which enables distinguishing between the occupied and unoccupied conditions and identifying human activities in a self-adaption environment. It is an ideal solution for high-accurate, self-regulation, privacy-protected, secure biotic radar systems in individual applications, such as smart home, human behave detecting, danger alarm.

Compared to the traditional PIR sensor, the Human stationary Presence Module has more sensitivity to human activities like standing, moving, and falling. And because the transmitting wave is millimetre-level, it will remain functioning even shelter block. Not like the PIR sensor short responding, the module keeps sensing people continuously which makes it quite useful during the living room, hotel, or even prison.

The module contains a standard self-learning algorithm, it can detect simultaneously, privacy-protectively, and it can manage different environments whether the location is a little noisy or extremely peaceful. Above that, it highly decreases the interference of non-living objects and the detect output is up to 95 % accuracy.

There is a two-array, high-performing antenna built on the module and it has fan-beam pattern beamwidth where the Horizontal is 90° and Vertical is 60° which makes its sensing area as high as 96m². Additionally, it even can sense micromotion. The module is very adaptable to the environment and it can maintain proper functioning even if the environmental factors are different. The output power is very low which ensures it is harmless to the human body even in prolonged exposure.
