Rancang Bangun Kompor Gas Cerdas Berbasis Internet Of Things (Iot) Menggunakan Aplikasi Blynk
ABSTRACT
Gas stoves are a type of stove commonly used by the Indonesian community for cooking. However, using gas stoves is associated with risks, such as explosions or fires, if not used cautiously. To address these issues, this thesis designs a system that can monitor and control gas stoves based on the Internet of Things (IoT). The design utilizes several sensors: the MQ-2 sensor as a gas leakage detector, the PIR sensor as a user activity detector when the stove is turned on, and the Flame sensor as an ignition flame detector. In addition to these sensors, the circuit is designed with a servo motor for manual or automatic stove shutdown control. Furthermore, a buzzer is used to warn about gas leakage from the gas cylinder. The sensor data is transmitted from the NodeMCU ESP32 to the Blynk application for monitoring and control. The testing results demonstrate that the device can monitor and control the gas stoves. The average voltage measurement of the MQ-2 sensor under normal conditions is 1.85 volts, and during gas leakage, it is 2.37 volts. The average voltage measurement of the Flame sensor under normal conditions is 0.19 volts, and when the stove is ignited, it is 3.08 volts. The average voltage measurement of the PIR sensor under normal conditions is 0.024 volts, and when there is user activity on the stove, it is 3.28 volts. The average data delivery delay to Blynk is 0.15 seconds. The automatic stove shutdown testing showed an average delay of 5 seconds. The control of stove shutdown through the Blynk application has an average time difference of 1.54 seconds.
