Implementation of Wireless Sensor Network as Fire Detector using Arduino Nano

At this time there are still many fires that occurred. One cause of this disaster is human negligence. Fire can cause damage to lives and financial loss. The first indication of fire is smoke and fire, or gases too. This paper presents the application of a fire detection system. This fire system will use Arduino Nano as a microcontroller and the wireless nRF24L01 as communication data. this system has 2 microcontrollers that have different functions. The first microcontroller will be used as the slave that detects fires by using fire, smoke and gas sensors. the second microcontroller will be used as a master that functions as an access point and is used to activate a fire warning in the form of a lamp and a buzzer sound. Tool design has a small size, efficient, easy to use and has met the system that has been designed without reducing the reliability and power of the system. In this study, we will make the slave consist of three parts with different locations.
