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. The combination of these sensors offers more precision in terms of diffused and direct solar irradiance. The open-circuit voltage Voc, cold, and hot side temperature of the Peltier are monitored to assess the solar irradiance. Also, the use of GPS and RTC module in the proposed system gives the exact location, time, and date of solar irradiance at a particular instant, which provides distinct features to the solution. The output signal is then processed through the microcontroller and transmitted to the cloud for analysis at the remote site.
