Low Power Forest Fire Detection

Abstract

Abstract: Fire detection and warning systems are critical for ensuring the safety of people and property. We present an innovative system for detecting and alerting fires that employs a combination of an MQ135 gas sensor, Arduino Uno microcontroller, and SIM900A GSM module. Its purpose is to identify the existence of smoke and other types of gases that are emitted during a fire and to provide real-time alerts to a pre-programmed set of phone numbers through SMS using the SIM900A GSM module. The system also triggers an alarm to alert people and the forest department in the vicinity of the fire. The MQ135 gas sensor is used to detect the presence of smoke and other gases in the air. The sensor's output is fed into the Arduino Uno microcontroller, which processes the data and triggers the alarm if the concentration of smoke or other gases exceeds a pre-set threshold value. The SIM900A GSM module is used to send real-time alerts to pre-programmed phone numbers through SMS, enabling swift action to be taken in case of a fire. We also use deep sleep mode to save power. We have divided the forest into various zones according to activity in that area.
