Abstract:

Automatic Pump ON/OFF based on Fire circuit is presented here is based on the readily available Flame Sensor, comparator IC LM393 and relay. The Flame sensor is used as the fire intensity detector while IC LM393 used as comparator. In the absence of fire, no fire on the flame sensor. As a result flame sensor stop conducting and water pump stays off. However, when there is fire on the flame sensor, flame sensor starts conducting and water pump is ON.

Application of the circuit:

Most of the flame sensor based circuits available in market use one or another kind of flame sensor which increases the cost and also require complicated circuitry around it. But this flame sensor based circuit uses readily available flame sensor as fire detector. The functioning of this Automatic Pump ON/OFF based on Fire circuit is to detect fire and automatically activate the water pump in presence of fire. Water pump is ON continuously indicating the presence of fire till there is fire.

Why this particular circuit:

Fire sensor used here as a fire detector. The circuit operates normally over a DC voltage of 5V which can be obtained by DC supply cable.

Explained working of circuit:

The basic idea behind the circuit operation is to turn ON water pump in presence of fire. The flame sensor is needed for this purpose. Flame sensor is device that converts heat to electric energy. Here, Automatic Pump ON/OFF based on Fire circuit works as fire detector while flame sensor turns on the water pump. IC LM393 is used as comparator. Flame Sensor output is connected as input to comparator.  Pin no. 4 of LM393 is pulled towards ground. Relay is used as a switch. When relay is activated, normally closed contact becomes open and normally open contact becomes closed. In normal condition, when there is no fire and water pump stays off. Now consider second scenario when there is fire, the water pump is ON in the presence of fire.

How to build:

First of all read the given manual thoroughly and study the circuit given in the figure. Also have look at PCB and components supplied along with the kit. Each component has to be soldered in its position on PCB.

Identification of resistors is done by color coding. The color band on each resistor corresponds to its exact value.

There are different methods in which values are defined on capacitors. But usually values are specified numerically on them.

Can you make out the whole working of circuit and are you able to identify each component separately as to where each of them has to be placed?

If yes only then proceed further to actually mounting and soldering the parts.

Not ICs but their sockets are to be soldered on PCB. This is to make mounting and dismounting of ICs easy while troubleshooting.

Start from left most corner of PCB and solder the components one by one on their correct position on PCB.

Before soldering any component see that you have placed it at its right position and with correct polarity. Give due attention to diodes and electrolytic capacitors as they are polarity dependent.

Do the soldering of other components in the same way while keeping in mind that components with long and sensitive leads like capacitors and transistors are soldered last.

Testing the kit:

After assembling and soldering of components on PCB, connect external DC power source of 5V.

For testing purpose manually hold fire over flame sensor. Water pump is ON in this case.

Now set the desired intensity at which you want detection of fire. This can be done by changing the resistive value of R2 variable resistor.

Install the unit at ceiling of room.
