Hi Angel, Understood. If follow the document, replace resistor with sensor band.But I have one questions. I measure the band resistance value without water on the band by mulimeter and the value around 11Mohm~13Mohm, And resistance value around 5Mohm~7Mohm with water leakage on the band. If follow the reference design, it means the resistance value around 11Mohm~13Mohm or 5Mohm~7Mohm between VDD and ADC. When resistance value changed, the ADC will detect the voltage on variation. The resistance value is always on variation(11Mohm~13Mohm or 5Mohm~7Mohm). It menas the voltage is always on variation at ADC site. How to know the voltage variation is cause lthe eakage? Because the resistance value is not with gap value when leakage. Thanks
