5.3 RECOMMENDATIONS FOR FUTURE IMPROVEMENT
For further study about counter system, the system can be improved by
solving the problem occurred by distance sensor. Calibration for sensor and bright
LED can be used to increase the accuracy of the distance sensor.
In addition, the study on programming to make the system more flexible is
required. This system can be upgrade where both sensors can differentiate the
direction of occupant after they stand between the sensors that caused an error.
Other than that, the negative value of the system can be eliminating on further works.
The systems will never count to negative value even there are error cause by sensor
or microcontroller. The failure of the system to detect person coming in or out from
the laboratory also can be improved by doing further research and adding new idea.
On further research, the idea to calculate height of visitor also can be upgrade so the
system is more reliable and accurate.
Moreover, any idea to design a system that can save power energy in a
building would be necessary to reduce power consumption and electricity bill. This
can avoid energy wasting when it not in use.
