Introduction:
The Fire Alarm System using Arduino and a Temperature Sensor is an automated system designed to detect rising temperatures indicative of a fire hazard. This system sounds an alarm when the temperature exceeds a preset threshold, alerting individuals to the potential danger. This project uses Arduino and a temperature sensor (like the LM35) to simulate a fire detection system on Tinkercad, a popular online simulation tool for electronics.
Project Overview:
In this project, a temperature sensor is used to monitor the ambient temperature. When the temperature rises above a certain level, which is typical in case of a fire, the system triggers an alarm. This setup is ideal for areas where fires need to be detected early to avoid property damage or danger to life. The project is simulated using Tinkercad, allowing users to visualize and test the circuit without physical components.
Components Used:
Arduino Uno:
The central microcontroller that processes sensor data and activates the alarm.
LM35 Temperature Sensor:
Used to detect the temperature of the surrounding environment. The sensor sends analog voltage readings to Arduino that correspond to temperature values.
Buzzer:
Emits a sound when the temperature crosses the set threshold, acting as the fire alarm.
LED (optional):
Can be added to indicate the status (e.g., green for normal, red for alarm triggered).
Resistors and Jumper Wires:
To create the necessary connections between the components.
Tinkercad Simulation:
This project is simulated using Tinkercad, which allows for virtual testing of the circuit and code.
Working Principle:
Temperature Monitoring:The LM35 temperature sensor continuously monitors the ambient temperature and sends this data as an analog signal to the Arduino.
Threshold Check:The Arduino continuously checks the value from the LM35. If the temperature reading exceeds a preset threshold (indicating a potential fire), it triggers the alarm.
Alarm Activation:When the threshold is crossed, the Arduino activates the buzzer, producing a sound to alert nearby individuals. Optionally, an LED can be activated to indicate the alarm status.
Safety Mechanism:The system ensures immediate response to temperature changes, allowing users to take precautions before the situation escalates.
Benefits:
Early Fire Detection:Detects potential fire hazards based on temperature changes, providing early alerts to prevent fire disasters.
Cost-Effective:The system uses inexpensive components like Arduino and LM35 sensor, making it affordable for homes or small offices.
Automation:Automatically triggers an alarm when the temperature threshold is reached, reducing human intervention in fire safety.
Real-Time Monitoring:Continuous monitoring and instant notification to keep users aware of temperature changes.
