Internet of Things (IOT) based automatic seawater distillation is intended to help meet the needs of coastal communities for clean water. The development of seawater distillation equipment from conventional to semiautomatic aims to facilitate the distillation of seawater so that this tool can optimally work according to its function and is easy to use. This study aims to develop a seawater distillation device by utilizing technology and system automation to increase the efficiency of the tool so as to facilitate the lives of coastal communities in meeting the need for clean water. By utilizing the NodeMCU Esp 8266 microcontroller as the main control to run several supporting controllers namely Temperature sensors, pH sensors, TDS sensors, and Ultrasonic sensors which are used to support automatic seawater distillation then processed with NodeMCU ESP 8266 to display count data to applications and several components which works according to the program that has been made, the advantages of developing this tool can make it easier for users because it can automatically monitor distillation from sea water and can be controlled using the blynk application as long as the system is connected to the internet network.
