Block diagram Explanation:

Here we are designing a System which will automatically detect any hazardous situation related to fire in the area. Also we are designing and building a fire fighting robot with fire extinguishing mechanism

  • Read the Light and temperature sensor data (Fire). Perform Signal conditioning on the signal. (If the signal is very low in µv).
  • Store the data in µC internal memory (RAM).
  • Display the parameters on LCD
  • Move the buggy in forward direction using the DC motor based model.
  • If fire detected, then stop the buggy and operate the fire extinguishing mechanism for 2 seconds.
  • For fire condition turn on Buzzer.
