2. The Turbidity Sensor Provides These Turbidity Measurements To The Washing Machine Or Dishwasher Controller, Which Determines The Time Of Each Wash Cycle. These Judgments Are Based On A Comparison Of The Purified Water Measurement (Measured At The Beginning Of The Wash Cycle) And The Wash Water Measurement At Of The Wash. 1. Turbidity Sensor How The Sensor Works: When Light Passes Through A Certain Amount Of Water, The Amount Of Light Transmitted Depends On The Amount Of Dirt In The Water. As The Amount Of Dirt Increases, The Amount Of Light Penetrating The Water Sample Decreases, And A Turbidity Sensor Measures The Amount Of Light Transmitted To Calculate The Turbidity Of The Wash Water. 4. The Small Breakout Lm358 Is Used To Amplify The Analog Input Signal And Adjust The Onboard Trimmer Potentiometer For Amplification. Two Leds On Board, Red Power Status, Green Digital Output Status Led (Not Very Bright) 3. By Measuring The Turbidity Of The Wash Water, The Washing Machine Can Only Wash Less Dirty Clothes For The Time Required, Thereby Saving And Allowing User To Save . 5. Default Analog Value Output, Switch The Jumper To Digital Output. Adjust The On-Board Potentiometer To Change The Analog Threshold., Weight: 0.0330693393 Pounds, Manufacturer: ximie
