VOC sensor for Urine Detection

by anhv on Wed Aug 14, 2019 12:27 pm

Hi,

I'm looking at VOC sensors from Adafruit and wonder if they can be used for Urine detection. Or are there more suitable choice of sensors for this use?

We have sensors that detect ammonia:

The ammonia concentration of fresh urine is fairly low, but bacteria break down the urea and create more ammonia as a waste product. That will probably be your best bet.
