Abstract/Summary

A microcontroller based six wavelength sunphotometer (EARTHSun) and a pyranometer (EARTHPy) was developed in this study. EARTHSun made used of Six (6) Intor® photodiodes with different wavelengths while EARTHPy made used of a BPW21 photodiode. EARTHPy was cross calibrated using a Kipp and Zonen ® CMP3 pyranometer using two calibration methods. The first method used correlation to calibrate the pyranometer and yielded a calibration constant of 387.68x ± 3.85, x being the raw voltage. The second method's calibration constant is 350.0996 ± 61.37 which is also multiplied to the raw
