Once again, the light sensor is not powerful enough to detect a difference in the light emission of the ''Dinoflagellates'', but the TSL2561 is still more sensible than the photoresistor used in the first attempt. It is a good option for somebody who would like to work in low light. | Once again, the light sensor is not powerful enough to detect a difference in the light emission of the ''Dinoflagellates'', but the TSL2561 is still more sensible than the photoresistor used in the first attempt.

==Third attempt== | |||
Finally I found a sensor that is sensible enough to read the low light of the 'Pyrocystis'. It is the [https://www.mouser.de/ProductDetail/ams/TSL237S-LF?qs=ishzoaUFYmTOJTeugUzKUw== TSL237S-LF], which is a Light-to-Frequency Optical Sensor. | |||

The wiring is pretty straight forward, but the code is a little bit more tricky if you are a beginner. I found one that I adjusted and it is now working well for the low light, and another one that works better with natural light. | |||
