Joybien mmWave 毫米波感測開發套件是一款毫米波(mmWave)雷達和藍牙低功耗(BLE)的擴充板，使用了 TI IWR1642 毫米波感測器做為核心，下載應用介紹。
毫米波是第五代行動通訊(5G)中解決頻段問題的一項技術。Joybien mmWave 毫米波感測開發套件將原本複雜的雷達感測數據經過微積分和 FFT 等計算後，搭配 mmWave Python SDK 輸出簡單的資料結構，例如範圍、速度或是角度值等。
《應用範圍》
- 不同應用，例如生命跡象偵測(VSD)，移動/人流偵測(PMB)，高精度量測(HAM)，需個別購買硬體，並非一套硬體可同時使用三種應用！
- 非接觸式的生命跡象偵測(Vital Signs Detection, VSD)，例如心律量測(Heartbeat Rate)或是呼吸速率量測(Respiration Rate)，量測距離在 30cm – 90cm。
- 移動/人流偵測(People Movement Behavior, PMB)，例如可量測到物件在雷達偵測範圍的相對座標、速度或是角度值等。量測範圍在 4x4m 區域(或是 16 平方米)。
- 高精度量測(High Accuracy Measurement, HAM)，例如高精準度的距離量測，量測範圍在 30cm – 3m，可達到毫米級的分辨率。
