Smart IoT CPO Storage Tank

Abstract Indonesia’s crude palm oil (CPO) production from year to continues increase, at the end of 2020 it reached 17.35 million tons, up 3.6% previous year. Increasing will result in more CPO stock and require good storage. The storage process that occurs is maintain temperature so quality not damaged. This regulation still done manually raises risk work accidents. purpose this research create a control system automatic volume measurement can be monitored smartphone. manufacture used ESP8266 NodeMCu microcontroller, sensor, proximity 1000-Watt heater. Programming Arduino IDE C++. study was an IoT Storage Tank design equipped with sensors microcontrollers. measured DS18B20 sensor had data accuracy 99.19% while HC-SR04 99.78%. Data obtained could seen through Thingspeak application computer or
