Dear Mr. Green,
I see you've been through a long journey of building a PAR sensor. May I ask if you have complete instructions on hand? If yes I'd really appreciate if you could share them.
If not, could you give me few pointers. I have few questions here. What is the purpose of Cosine diffuser and how do you use it? Is the Photodiode VTB8441BH submersible? I was thinking to put the sensor into the aquarium for constant monitoring. Will this work with Miniature Solar Cell - BPW34
? I'd prefer to use the latter one since it is much smaller.
Also, what is the algorithm to calculate the PAR value from the sensor reading?
Thanks a lot,
