Description Arduino uses serial communication to give instruction to the gsm. GSM module has a sim slot where we insert a sim. only 2G sim can work with the module. in the final year project ece you need to mention all the detail about your project. so you need to know all the detail. we are sharing all the details. you need to read carefully to make and understand this major project for ece. When the flame sensor detects anything it will notify the Arduino and Arduino send an instruction to the sim900 gsm module to send a message to the given number. now, I got a message ” fire alert” now I will send a message to the water pump which will control the fire at the spot. and wait for the next message. if I didn’t get any message it means the water pump controls the fire and then I will send a message to turn off the pump. and if the water pump is not successful to control the fire then it will send a message to my number again for fire alert. The working is very simple and the working principle is to turn on and off the system and monitoring via gsm message. You need to send the message only via your mobile phone in the response to the message received.
