PERANCANGAN SISTEM PENGISIAN GALON OTOMATIS PADA DEPOT AIR MINUM ISI ULANG BERBASIS ESP 32

Abstract

Depots water are businesses that process raw water into drinking water and sell directly to consumers. the current condition is that there are still drinking water depots operating manually in filling gallons, causing operators to pay attention to the air level in filling gallons, errors in the filling process can cause water to overflow from gallons because the button is pressed too late or the gallon is not fully filled because the button is pressed too quickly. The purpose of this study is to create an automatic gallon filling system at an ESP32-based drinking water depot, this control system will work if the gallon is placed in the filling box, in the charging box there is an infrared sensor to detect the presence of gallons, when gallons are detected on the infrared sensor, The ESP32 microcontroller will send a signal to the solenoid valve to open the filling valve. If the air flow on the waterflow sensor has met, the ESP32 microcontroller will send a signal to the solenoid valve to close the faucet. This control system can also calculate the number of fills that have been made and will be sent to the Thinger.io web server. The types of sensors used in this research are infrared obstacle sensors, waterflow sensors, and solenoid valves. The infrared obstacle sensor has a detection distance of 3-80 cm. The waterflow sensor calculates the amount of air that comes out of each rotor in its rotating waterflow. For the air flow that comes out through the waterflow sensor at the setpoint setting of 16.4, the setting at the setpoint greatly affects the filling of gallons. At the setpoint 16.4 managed to fill the gallon with a volume size of 19 liters, the duration of filling the gallon varies from 130 seconds to 162 seconds, this is due to the air velocity passing through the water flow sensor is not constant (not fixed). After successfully filling the 19 liter gallon, ESP32 will send the data from the gallon filling to the Thinger.io webserver. for data sent to thinger.io in filling gallons at a setpoint of 16.4 between 16,133 liters to 18.27 liters
