When there is a fire breakout in
the room the temperature increases. This ultra compact and low cost fire alarm
senses fire breakout based on this fact.
Hardware Requirement
BC 177
BC108
BC128
9V SPDT Relay
Diode (1N4007)
Circuit diagram
Working
Transistor BC177 (Q1) is used as the fire sensor here. When the
temperature increases the leakage current of this transistor also increases.
The circuit is designed so that when there is an increase in the leakage
current of Q1, transistor Q2 will get biased. As a result when there is a fire
breakout the transistor Q2 will be on. The emitter of Q2 (BC 108) is connected
to the base of Q3 (AC 128). So when Q2 is ON Q3 will be also ON. The transistor
Q3 drives the relay which is used to drive the load ie, light, bell, horn etc
as an indication of the fire. The diode D1 is used as a freewheeling diode to
protect it from back EMF generated when relay is switched.
Notes
The Preset R1
can be used to desired temperature level for setting the alarm ON.
This is not a
latching alarm, that is; when the temperature in the vicinity of the sensor
decreases below the set point the alarm stops.
The circuit can
be powered using a 9V battery or a 9V battery eliminator.
All capacitors
are electrolytic and must be rated at least 10V.
The load can be
connected through the C, NC, NO points of the relay according to your need.
The calibration
can be done using a soldering iron, and a thermo meter. Switch ON the power
supply. Keep the tip of soldering iron near to the Q1. Same time also keep the
thermometer close to it. When the temperature reaches your desired value adjust
R1 so that relay gets ON. Done!
