 WORKING OF EACH COMPONENT
 1. Flame sensor: A flame-sensor is one kind of detector which is mainly designed for detecting
as well as responding to the occurrence of a fire or flame. This sensor detects flame
otherwise wavelength within the range of 760 nm 1100 nm from the light source .This sensor
can be easily damaged to high temperature. So this sensor can be placed at a certain
distance from the flame. These sensors are mainly used in fire alarms, fire fighting robot,
fire detection, hydrogen stations etc.
 2. Buzzer: An audio signaling device like a beeper or buzzer may be electromechanical or
mechanical type. The main function of this is to convert the signal from audio to sound.
Generally, it is powered through DC voltage and used in timers, alarm devices, printers,
alarms, computers, etc. Based on the various designs, it can generate different sounds like
alarm, music, bell & siren
 3. BD140:It is a famous PNP type transistor, it is used in many electronics circuits, this
transistor can handle current upto 1.5A or 1500mA, due to which it can be used to drive
loads upto 1.5A in electronic circuits, for example high power LEDs, relays, motors and
more, with these features it has lots of other features like its high collector emitter and
collector base voltage that is 80 volts, make it an ideal transistor to use in circuits using 80
volts DC or below 80 volts
 4.RESISTORS:First of all, Resistors are electronic components that impede the flow o electric
current. They are commonly used in circuits to control the amount of current or voltage in a
circuit. The resistance value of a resistor determines how much it restricts the flow of
electric current. In the case of a 1k resistor, it allows more current to pass through
compared to higher resistance values, such as 10k (10 kilohms) or 100 (100 kilohms)
resistors.
 5. Switch: An electric switch is an electromechanical device tha
connects or disconnects the electricity supply to a circuit. Electric
switches are very important in electrical circuits because, without
an electric switch, all the devices we are usingare useless and
cannot be operated without a switch.
 6. Water pump: 3V Vertical water pump is a kind of DC micro
submersible pump. Equipped with male and female Dupont line
connectors, it can apply to the fountain used in many situations
with much convenience. They are operates With low noise and have
good performance. They are Made by engineering plastics to
protect it from exploringalso they are Small and easy to install.
 WORKING OF THE CIRCUIT
 The flame sensor detects the fire and gives a negative output on the
DO (Digital Output Pin) pin, which is insufficient to turn on the water
pump and buzzer.
 So, we have used a transistor to amplify the output signal of the
flame sensor.
 We have connected a buzzer and water pump with the transistor
collector pin.
 Now when the flame sensor detects the fire it will give a negative
output which will turn on the transistor and then the transistor will
turn on the buzzer and the water pump.
 This is how the whole circuit works.
RESULT
APPLICATION

 1. Industrial Settings: The fire extinguishing robot can be deployed in

industrial environments where fires pose a significant risk. It car through
complex machinery and tight spaces to detect and suppress fire promptly,
mínimizing damage to equipment and ensuring the safety personnel.
 2. Residential Buildings: Residential buildings can benefit from the
deployment of fire extinguishing robots, especially in multi-story
apartments or homes where traditional fire extinguishing methods may be
challenging to implement. These robots can provide an additional layer of
fire protection, complementing existing fire safety measures.
 3. Hazardous Environments: Environments with hazardous materials or
conditions, such as chemical plants or oil refineries, can utilize fire
extinguishing robots to mitigate the risk of fire-related accidents. These
robots can operate safely in hazardous areas, reducing the exposure of
human
 LIMITATIONS
 1. Limited Fire Suppression Capacity: While effective for small to
moderate fires, the fire extinguishing robot may have limitation in
extinguishing large-scale fires or fires fueled by highly flammable
materials. In such cases, supplementary firefighting measure required.
 2. Navigation Challenges:The robot's ability to navigate through
complex environments may be hindered by obstacles or debris,
affecting its response time to fire incidents. Continuous improvements
in navigation algorithms and obstacle avoidance mechanisms are
necessary to address these challenges.
 3. Maintenance and Reliability: Regular maintenance of the robot's
components, such as sensors, motors, and batteries, is essential to
ensure optimal performance. Additionally, reliability issues, such as
sensor malfunctions or mechanical failures, may arise over time,
requiring timelv repairs and replacements to maintain the robot's
FUTURE SCOPE
