About 7% of all house fires start in a bedroom. It leads to damage of all plush objects and also loss of life. To avoid that or to minimize the damage caused by fire outbreak an IOT technology is used to control such a kind of risk. NodeMcu based IoT fire detector is the solution for this kind of issue. In this model, we have fitted a fire indicator by making practical and effective use of NodeMCU ESP8266 which is connected with a smoke sensor and a Flame sensor. The smoke sensor detects if there’s any smoke produced because of ingesting any type of gas and Flame sensor is for fire detection. Buzzer interfaced with it makes an alert sound and for the prevention, it is enabled with the automatic Water sprinkling system. A fire warning can also be activated by a little smoke from the flame of burning candle or fire lamps or a burning cigarette which may be used in any family. The buzzer gets stopped itself at whatever point the temperatures falls to comfortable indoor temperature and the amount of smoke decreases. NodeMCU fire and Smoke finder serves best because at whatever point it indicates fire or smoke, then it immediately alarms the admin or user about the fire through the Blynk App. At whatever point a fire happens, the user gets the alert notification through smart phone.
