Fire Alert using Push Mobile Notification - IOT

Updated: Apr 1

In this article, we are going to discuss how to interface the #raspberry pi board with a fire alert system and send mobile notifications to it by using push bullet service. A fire sensor is a device that is used to detect fire or flame. It is very important to use this type of sensors where there is a chance of a fire occurring. We can use even for our household purposes also where there might be any chances of occurring fire accidents. So let's get headed towards the project and understand the working in detail along with the circuit diagram and codes.

Raspberry Pi

The Raspberry Pi is a low-cost, chip machine that enables a regular mouse and keyboard attached to a device monitor or TV. It is a lightweight, functional computer that allows individuals of all ages to explore programming and study how to program in languages such as python.

Fire Sensor

Fire Sensor is used for sensing smoke and/or heat by an automatic fire detection arrangement. These systems react to the existence of fire-related smoke or incredibly high temperatures. The unit will transmit a signal to the warning system after the unit has been triggered to execute the programmed response for that region.

USB Cable

USB cables are directly connected to external equipment, such as cell phones, cameras, video recorders, and machines/printers, to computing devices. The primary function of these cables is to capture or transfer data from one computer to the next efficiently, easily, and efficiently.

Jumping Wires

Jumper wires are used to establish a connection between different elements in the circuit and #Raspberrypi board. There are two types of wire, male and female. The male wires have ends that can be connected to other ends and the female wires are the ones that have the receiving end.

Circuit Diagram



The fire #sensor has four pins which are A0(analog pin), ground, VCC(can be 3.3v/5v depending on the module), and D0( digital output pin). In addition to these pins, the module has LEDs for power and D0 output. The D0 led glows when the sensor detects fire. Also, we have a #potentiometer in the fire sensor which allows voltage to flow as per the required amount while functioning.


We connect these pins with a raspberry pi board with different pins on it. The D0 pin of the fire sensor is connected to the Raspberry Pi GPIO. The ground and VCC pin of the fire sensor is connected to the respective terminals of the Raspberry Pi board.


In the fire sensor, the fourth pin is the analog pin(A0) which can not be connected to the Raspberry Pi directly. So if one wants to use the analog pin an external analog to digital converter is required for the Raspberry Pi GPIO.

Working


First of all, you need to create an account in the #push bullet services by simply logging in by your account. Completing the few necessary steps and you are done. Next, connect all parts and powerup the circuit.

After entering the code on the module then add push bullet app to the module.

Then next we need to test our module with flame. when we place the sensor near the flame we will get a notification through the push bullet app on our mobile.
