can i use bpx43 with Arduino to measure solar radiation MJ /m2 /day
Please post a link to the bpx43 datasheet
Hi @omerahmed .
The wavelengths of visible light range from 400 nm to 750 nm.
This sensor has a response curve (page 4) that goes from 400 nm to 1100 nm.

The BPX43 is a phototransistor, which is not suitable for measuring insolation.
You will want to use a photodiode or PV cell. See this overview on DIY instruments: Measuring Sunlight at Earth’s Surface: Build Your Own Pyranometer
