3. Background of the Study

4. 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.

5. Objectives of the Study
Improvise a circuit;
Gather the materials and tools needed for the
construction;
Construct the improvised device;

6. Objectives of the Study
Test the functionality of the device on the
basis of water detection and alarm system.

7. Significance of the Study
Help warn people of an incoming
flood, especially at night
Decrease the casualties and damage of
properties

8. 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

9. 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

10. Materials and Methods
Schematic Diagram of the Circuit

11. Materials and methods
Construction of the Device:
Improvised a Circuit
Gathering of the Device
Materials
Attaching the megaphone
to the circuit
Assembling of the Device

12. Materials and Methods
Testing of the Device:
Sensors are submerged in water
The megaphone made the
expected alerting sound

13. MATERIALS AND METHODS
Operation of the Device:
1. Electrodes are
immersed in
water, simultaneou
sly.
2. Circuit is triggered
3. Megaphone
Wails

14. Materials and Methods
Gathering of Data:
Evaluation of the Device
(Functionality, Efficiency, Safety, and
Aesthetics)
Calculation and Recording of Gathered
Data

15. RESULTS OF EVALUATION
I. 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.

18. 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.

19. ANALYSIS OF GATHERED DATA
The researchers are focusing on improving
its appearance to achieve a higher rating
and for it to attract more buyers.

20. the device fulfills the main objective of the
study.
It can efficiently alert people when there is a
flood occurring.
CONCLUSIONS AND RECOMMENDATIONS

21. 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)
