Background of the Study

Background of the Study

The Philippines has two

seasons, wet and dry.

unexpected tropical

storms occur.

A lot of casualties are left

when the typhoons

strike.

Objectives of the Study

Improvise a circuit;

Gather the materials and tools needed for the

construction;

Construct the improvised device;

Objectives of the Study

Test the functionality of the device on the

basis of water detection and alarm system.

Significance of the Study

Help warn people of an incoming

flood, especially at night

Decrease the casualties and damage of

properties

Scope and Limitations

Limited to one pair of sensors

For detection of flood

electrical power source (1.5V batteries)

Positioning or placing of the device depends

on the area

Materials and Methods

Materials Needed:

1 Megaphone

2 Resistors(10KΩ and

56 K Ω)

1 Integrated Circuit

(555 timer)

3 Capacitors (two

0.01 µF and a 47µF)

Wires (At least one

meter)

6 1.5V batteries

Materials and methodsConstruction of the Device:

Improvised a Circuit

Gathering of the Device

Materials

Attaching the megaphone

to the circuit

Assembling of the Device

Materials and MethodsTesting of the Device:

Sensors are submerged in water

The megaphone made the

expected alerting sound

MATERIALS AND METHODSOperation of the Device:

1. Electrodes are

immersed in

water, simultaneously.

2. Circuit is triggered

3. Megaphone

Wails

Materials and MethodsGathering of Data:

Evaluation of the Device

(Functionality, Efficiency, Safety, and

Aesthetics)

Calculation and Recording of Gathered

Data

RESULTS OF EVALUATIONI. Functionality and Efficiency

The device rings when in

contact with water.

The device stops ringing when

already away from water.

The electrodes are consistent in

sensing water.

The device is user-friendly and

easy to use.

Analysis OF GATHERED DATA

Those who evaluated the device:

Think it is efficient in alerting people in case

of flood

Think it is safe to use.

ANALYSIS OF GATHERED DATA

The researchers are focusing on improving

its appearance to achieve a higher rating

and for it to attract more buyers.

the device fulfills the main objective of the

study.

It can efficiently alert people when there is a

flood occurring.

CONCLUSIONS AND RECOMMENDATIONS

CONCLUSIONS AND RECOMMENDATIONS

It is recommended:

to use a larger siren for a larger range of

homes to be alerted

To use a 220-Volt source

to incorporate the power-utilization property

of emergency lights (in case of blackouts)
