SEN 0189 Turbidity sensor temperature compensation
jason.owens 2019-05-22 04:13:03 2471 Views2 Replies Hello Everyone,
I'm currently using the SEN 0189 Turbidity sensor for a project and am working on some calculations to compensate for the voltage drift due to temperature. So far, I have been able to make an equation I can use, which matches the overall behavior of the Voltage Temperature plots shown on the Wiki page, but in order to apply it correctly, I need to know at what temperature the Voltage to NTU equation/plot was made. My best guess is around 27 C but can someone tell me what the correct temperature should be? Once I know this, I can compensate my voltage measurements to the right temperature and then plug into the NTU equation to get the correct values.
Thank you,
Jason O
