yea, i know i needed the op amp, but i wish to log 1 set of data without the op amp first then only proceed with op amp, however i do not understand what the logged output represents, and how to convert them into irradiance value. my cf is also rated at 1v 100mA under full sunlight

just found out that op amps cost around 8usd in my country, and i have 11 sensors to-be-amplify, so does that means i need to purchase 6 of them?
