Abstract

Technological developments from time to time develop rapidly, not because of ease of use but accuracy in the world of work. One of them is in the world of agency work at the Jembrana Class II Climatology Station. Regarding the tools at the Jembrana Class II Climatol-ogy Station, it is still classified as a manual, one of the tools in question is the Open Pan Evaporimeter. The application for this tool is strived to make it easier for observations to take place, therefore an IoT-based monitoring system tool is made to read the occurrence of evaporation on the device. The VL53L0X sensor is used to measure the water level and the DS18B20 sensor is used to measure the water surface temperature. The creation and display of data is used by the Thingspeak web server, this makes it easier to read measurement data. Evaporation data was taken for two months from May to June, in one day three observations were made. The first observation was carried out at 07.30 WITA - 07.51 WITA, the second observation was carried out at 13.30 WITA - 13.51 WITA, and the last observation was carried out at 17.30 WITA - 17.51 WITA. Comparative data in May for monitoring system tools obtained a comparative value of 94.0 mm for manual tools, 75.2 mm for automatic tools and comparison data in June for monitoring system tools, obtained a comparative value of 127.0 mm for manual tools 108.0 mm for automatic tools.
