A biological information sensing module and a biological information sensing method are disclosed. The biological information sensing module disposed on a housing of an electronic apparatus includes an optical sensing unit. When the optical sensing unit is pressed and moved from a first default position to a second default position, the optical sensing unit enters into a sensing mode to provide a biological sensing signal. When the optical sensing unit is pressed and moved to a third default position, the biological information sensing module enters into a warning mode to provide a warning signal. The displacement between the first default position and the third default position is larger than the displacement between the first default position and the second default position.本發明揭露一種生物資訊感測模組及生物資訊感測方法。生物資訊感測模組設置於電子裝置的殼體上並包括光學感測單元。當光學感測單元被按壓而由第一預設位置位移至第二預設位置時,光學感測單元進入感測模式,以提供生物感測信號。當光學感測單元被按壓而位移至第三預設位置時,生物資訊感測模組進入警示模式,以提供警示信號。第一預設位置至第三預設位置的位移量大於第一預設位置至第二預設位置的位移量。1‧‧‧生物資訊感測模組10‧‧‧表面12‧‧‧光學感測單元E1‧‧‧第一導電電極E2‧‧‧第二導電電極120‧‧‧光感測器122‧‧‧光發射器
