An electronic device includes a light source and an optical sensor. The light source emits a light having a maximum light intensity at a first wavelength A. The optical sensor has a maximum response value at a second wavelength B and receives a reflected portion of the light from an object. The integrated value of the light intensity from a wavelength of 380 nm to a first wavelength A is I1, the integrated value of the light intensity from the first wavelength A to a wavelength of 780 nm is I2, and the first wavelength A, the second wavelength B, the integrated value I1, and the integrated value I2 satisfy the following equation: (B-A) * (I2-I1) gt; 0. 一种电子装置包括一光源及一光学传感器。光源发射在一第一波长A中具有最大光强度的一光线。光学传感器在一第二波长B中具有最大响应值，且接收来自一对象的该光线的反射部分。从波长380纳米到第一波长A的光强度的积分值是I1，从第一波长A到波长780纳米的光强度的积分值是I2，且第一波长A、第二波长B、积分值I1，以及积分值I2满足下列算式：(B-A)*(I2-I1)>0。
