For measuring the uMol/m2/s we would need something like this quantum meter. I called with the company and they said this meters are not suitable for measuring LED light. This had something to do with the calibration of the device and our LEDs using blue and red LEDs. Later Carlos found out that you can use is but then have an error marge of approximate 10%. I think I could also make something with the sensor we have and an arduino and then calibrate this with a known light source, maybe a 100W lightbulb.
