Hi @chesse20,

try doubling the intergration time until you get a signal. You have it currently set to 20000 micro seconds.
Also you mentioned measuring something that isn't water. Does that mean under other conditions it does work?

Cheers,
Andreas

changing the integration time(from 20k to 190k) and changing the liquid from tea to water to tea doesn't seem to change the output from anything but noise
