Fire is one of the disasters that often occurs due to human negligence, with significant losses both in material and human casualties. This study aims to design and implement a fire detection system based on the Arduino Uno microcontroller that combines three main sensors, namely the TMP36 temperature sensor, the MQ-2 gas sensor, and the LDR light sensor. This system is designed to provide early warnings when early indications of fire are detected such as temperature increases, the presence of dangerous gases/smoke, and abnormal increases in light intensity. Test results show that the system is able to respond to dangerous conditions quickly by activating the buzzer as an alarm and displaying parameter information in real-time via a 16x2 LCD. This system has proven effective and can be applied to high-risk environments such as laboratories, homes, schools, and industrial facilities
