    • A turbidity sensor for use in a machine for washing articles, e.g., a washing machine (400). The turbidity sensor comprises a light source (210) for emitting light. The emitted light has a radiant intensity which is variable. The sensor further comprises a light-sensitive element (220) for receiving light emitted from the light source (210). The light source (211) and the light- sensitive element (220) are positioned relative to each other so that, when the light source (210) is in operation, light emitted from the light source (210) can propagate through a washing liquid contained in the washing machine (400) on its way to the light sensitive element (220). The light-sensitive element (220) is configured to measure the radiant intensity of light received at the light-sensitive element (221). Furthermore, the sensor comprises a controller (230) which is communicatively coupled to the light source (210) and the light- sensitive element (220). The controller (230) is configured to adjust the radiant intensity of the light emitted by the light source (210) in dependence of the measured radiant intensity of light received at the light-sensitive element (220).
    • 一种用于洗涤物品的机器的浊度传感器,例如洗衣机(400)。 浊度传感器包括用于发光的光源(210)。 发射的光具有可变的辐射强度。 传感器还包括用于接收从光源(210)发射的光的光敏元件(220)。 光源(211)和感光元件(220)相对于彼此定位,使得当光源(210)工作时,从光源(210)发射的光可以通过洗涤液体 包含在洗衣机(400)中的光敏元件(220)上。 感光元件(220)被配置为测量在光敏元件(221)处接收的光的辐射强度。 此外,传感器包括通信地耦合到光源(210)和光敏元件(220)的控制器(230)。 控制器(230)被配置为根据所测量的在光敏元件(220)处接收的光的辐射强度来调节由光源(210)发射的光的辐射强度。
