Information from the abstract
A low-cost and portable photometer was developed based on the ESP32 microcontroller integrated with a BPW34 silicon photodiode for the colorimetric determination of iron (Fe) and phosphorus (P) in fertilizer samples. The BPW34 sensor provided broad spectral responsivity in the 400–1100 nm range, rapid response (
