Abstract – Measurement of the intensity of solar irradiance is essential for designing renewable energy systems and atmospheric science. A low-cost, IoT-enabled pyranometer is proposed in this paper for data logging. The pyranometer is designed to measure the solar irradiance of spectral range from 300nm to 2800nm and hence covers UV, IR, and visible spectral ranges. The pyranometer exploits the phenomenon of thermoelectric sensing and photo sensing to measure solar irradiance. Peltier
module TEC1-12706 with BPX65 silicon photodiode is used for this purpose.

Abstract
In this manuscript, a smart, IoT-enabled, solar-based datalogger, which can measure AC and DC voltage and current of solar panel accurately is presented. Combination of stand-alone current and voltage sensors are used to measure to develop the datalogger. The datalogger can measure the current non-invasively, without introducing disturbance to the circuit under test. The PCB is fabricated, and measurements have been made to evaluate the system’s performance. The results demonstrate that sensed values give maximum accuracy compared to manually tested values.
