Fluid color detection #18

Closed garudaonekh closed 2 years ago

garudaonekh commented 2 years ago

Hi, I want to use this chip to detect color of water when I apply some reagent for aquaculture water parameter testing. For example, measure the Ammonia amount in the fish tank. Is this chip recommended for this purpose?

might work, no idea :)

@garudaonekh I've thought about this in the context of detecting color of a liquid - I'm guessing it will probably work for color detection of liquids under normal lighting conditions if you increase the integration time; however, I'm not sure if it will be sensitive enough to measure ammonia concentration in water for your use-case. For that, probably best to use a pH sensor as long as you know what else is in the water. Curious to hear back if you give this a try and how it goes.
