Rancang Bangun Sistem Otomatis dan Monitoring Ruangan Dapur dari Kebakaran Berbasis Internet of Things

Abstract

One of the fires that occurred in the kitchen was an LPG gas leak. To prevent fires from occurring, there was a need for a tool that could dispose of LPG gas leaks in the kitchen. From this problem, a system and tool was created using a Wemos D1 Mini microcontroller which was connected to the MQ-2, DHT 11, IR Flame and PIR sensors and the Blynk application for monitoring remotely with internet of things technology. For the MQ-2 sensor, when it detects gas above 200 ppm, an alarm will sound and activate 1 blower and will activate 2 blowers when it detects gas above 700 ppm. Apart from that, the tool made is also equipped with automatic fire extinguishing settings with an IR Flame sensor, temperature settings with a DHT 11 sensor and light settings with a PIR sensor. The systems and tools created have the benefit of preventing early fires in the kitchen.
