In industries, shops, malls, residential complexes, parking lots, etc., fire detectors perform a crucial function. They can help save lives by assisting with the early detection of fire or smoke. Commercial fire detection systems typically use a buzzer or siren to signal an alarm.

Utilizing a temperature and smoke sensor, we have created an IOT-based fire alerting system that not only signals the presence of a fire at a specific location but also sends pertinent information.

Introductory Concept

With the aid of sensors, electronics, software, and connection, the Internet of Things (IoT) is essentially a network of “things” that allows physical objects to share data. No human involvement is necessary with these systems. We may communicate LIVE information, such as temperature and smoke value sensed by a specific device, to the fire department using this Arduino fire alarm system that uses temperature and smoke sensor technology.

Sensor Involvments

Temperature and smoke sensors are used in the IOT-based fire alerting system. An ADC convertor transforms the analogue signals received at the sensor end into digital signals before sending them to the Arduino microcontroller. When the temperature and smoke levels reach a predetermined level, the microcontroller is programmed to activate the buzzer.

Arduino simultaneously transmits the data to the ESP8266 Wi-Fi module. A chip called ESP8266 is used to link microcontrollers to Wi-Fi networks. The following information will then be sent by the ESP8266 to the IOT website so that authorised individuals may take the necessary action to put out the fire.

• Temperature (in Degree Celsius)
• Smoke Value (in Percentage)
• Device ID
• Date and Time Stamp

Device ID is the distinctive ID assigned to a device to aid employees in obtaining information about the area where the fire is detected.

The Wi-Fi module has to be linked to a Wi-Fi zone or a hotspot in order for this Internet of Things-based fire alerting system to function. Additionally, this project is carried out without the IOT module. We have utilised a GSM module in place of an IOT module so that when the buzzer is switched ON, an SMS is sent.
