DEVELOPMENT OF IoT SYSTEMS FOR FIRE DETECTION TOOLS USING ESP 8266 AND TELEGRAM NOTIFICATIONS

Abstract

This research describes the process of making and developing a fire detection system using IoT
technology. The background for making this tool is because the existing tool at the research site,
namely at the Captive Power Plant of PT Indorama, is still a conventional device with an ordinary
smoke sensor system and notifications only via a buzzer. This system combines telegram
notification mode. Using three sensors namely temperature sensor, smoke sensor and fire sensor
is a very effective combination as an early warning system. The test results show that the system
provides notification via telegram when there is a significant increase in temperature above 31o
C. The smoke sensor is tested with three smoke conditions, namely thin, medium and thick with
a value of 704-803 ppm. The sensor response is less than 2 seconds, notification instructions to
telegrams are sent directly without any delay. In the fire sensor test, six test conditions were
carried out with variations in distance ranging from 10-100 cm, the sensor response was under 2
seconds, immediately activated the buzzer and a telegram notification was sent. The results of
this study contribute to the hope that with the three sensor combinations the security layer will be
more optimal and in real terms it can be used in industrial buildings which are prone to fire.
