Introduction

The TSD-10 module is used to measure the turbidity (amount of suspended particles) of wash water in washing machines and dishwashers. The optical sensor for washing machines is a measurement product that utilizes the refraction of wavelengths between a phototransistor and a diode to measure the density of turbid water or the concentration of impurities. By using a phototransistor and a photodiode, the washing machine optical sensor measures the amount of light from the light source to the light receiver to calculate water turbidity. The operating principle of this sensor is that when light passes through a water sample, the amount of light transmitted through the sample depends on the level of dirt in the water. As the dirt level increases, the amount of transmitted light decreases. The turbidity sensor determines the turbidity of the wash water by measuring the amount of transmitted light. These turbidity measurements are provided to the washing machine controller, which uses them to determine the wash duration for each wash cycle. These decisions are made based on a comparison between the clean water measurement (taken at the beginning of the wash cycle) and the wash water turbidity measurement taken at the end of each wash cycle. By measuring the turbidity of the wash water, the washing machine can wash only as long as necessary under light soil load conditions, thereby saving energy and reducing electricity costs for users.
