Ketersediaan instrumen yang tidak cukup dan kurang fungsional untuk mengukur radiasi matahari, menggunakan sensor kurang baik di daerah tropis, khususnya di Indonesia. Perancangan sistem monitoring intensitas radiasi matahari masih menggunakan perangkat yang konvensional. Perancangan sistem monitoring intensitas radiasi matahari menggunakan sensor Solar Power Meter SPM1116SD beserta sensor DHT11 (temperatur dan kelembaban). Perancangan berbasis mikrokontroler NodeMCU yang dapat ditampilkan di desktop mobile phone dengan adanya Internet of Things (IoT). Berdasarkan hasil pengujian yang dilakukan di Laboratorium Energi Terbarukan dari pukul 08.00-16.00 WIB, diperoleh intensitas radiasi matahari tertinggi yaitu 920 W/m2, dengan range temperatur 20⁰C-33⁰C, serta range kelembaban 33%-65%. Alat ini dapat digunakan pada cuaca yang tidak normal, di mana pengujian dilakukan pada temperatur 60⁰C dan kelembaban mencapai 5 %, pada temperatur 14⁰C dan kelembaban 88 %. Pengujian ini dapat dimanfaatkan secara langsung mengenai karakteristik nilai radiasi suatu daerah untuk kebutuhan pengguna. Kata kunci: Irradiance meter, Solar Power Meter SPM1116SD, temperatur, kelembaban, Internet of Things (IoT).

The availability of inadequate and less functional instruments to measure solar radiation, using sensors is not good in the tropics, especially in Indonesia. The design of the monitoring system of the intensity of the radiation in the sun is still using conventional devices. The design of the mono-radiation intensity 4 monitoring system using solar sensor SPM1116SD along with the DHT11 sensor (temperature and humidity). NodeMCU microcontroller based design that can be displayed on a desktop mobile phone with the Internet of Things (IoT). Based on the results of tests carried out at the Renewable Energy Laboratory from 7 to 108: 00-16: 00 WIB, 1 obtained the highest radiation intensity of 8 sun, which is 920 W / m20, with a temperature range of 20⁰C-33⁰C, and a humidity range of 33%-65%. This tool can be used in abnormal weather, where the test is carried out at a temperature of 60⁰C and humidity reaches 5%, at a temperature of 14⁰C C and 88% humidity. This test can be used directly regarding the characteristics of the radiation value of an area for user needs. Keywords: Irradiance meter, SPM1116SD Solar Power Meter, temperature, humidity, Internet of Things (IoT).
