    • A soil moisture sensor uses a non-collimated light source and a photosensor, respectively, mounted at the foci of a transparent ellipsoidal plastic body. The dimensions of the body are such that emitted light rays are internally reflected toward the photosensor at the surface of the ellipsoid if the surface is dry, but refracted outwardly of the body when the surface is wet. The amount of light reflected onto the photosensor is thus a measure of the amount of moisture at the surface of the sensor. Direct illumination of the photosensor by the light source is prevented either by interposing opaque electronic components between them on a circuit board, or by taking advantage of light source characteristics to minimize the amount of transmitted light. If a circuit board is used, it is completely encapsulated against moisture penetration by fixing it in a carrier and molding the body around and onto the carrier to form a monolithic unit with the carrier and circuit board.
    • 土壤湿度传感器分别使用安装在透明椭圆形塑料体的焦点处的非准直光源和光电传感器。 身体的尺寸使得如果表面是干燥的,则发射的光线在椭圆体的表面处朝向光传感器内部反射,而当表面是湿的时,其被折射到身体外部。 因此,反射到光传感器上的光量是传感器表面的水分量的量度。 通过光源直接照射光传感器可以通过在电路板之间插入不透明的电子元件,或通过利用光源特性来最小化透射光的量来防止光传感器的直接照明。 如果使用电路板,则通过将其固定在载体中并将体成型在载体上并与载体和电路板形成单片单元,从而完全封装防潮湿渗透。
