3-in-1 Disaster Alert System using arduino


I really your help. I’m just a beginner and really don’t understand much of this programming stuffs. My friend help me to make a diagram though I don’t know how to explain how the diagram works. Please help me in explaining how this diagram works


So from what I can tell, this 3 in 1 disaster system measures the flam, vibration and distance of an atmosphere. I dont understand what the sim module would be used for. If there was a speaker or something then it could be used to give audio feedback like “Fire Fire!!!” or “Earthquake!”, something like that. Without seeing the code I cant be certain. Who created this project, you or your friend. Could you explain what exactly the purpose of this is and how it works. _f you could provide the code that would be great too. :smiley:
