Weekly Progress
Last week,Our Habit Thai group had more clear about the mosquito trap like we had a
certain function that make us engineer team can design a circuit and seriously find an
information.And this week our engineer team have to define a size of PCB and explain a shape of a
paddle we use to be an information for a designing team to be able to design a characteristic of
the product.
Mosquito trap - Our work is to count a mosquito. What we're thinking is 2 types of sensors
1.light sensor 2.capacitive sensor using a magnetic field. After we consulted with our engineer
group we would like to use capacitive sensor because it has more sensitivity.And about to count a
mosquito that has a small size we have to design a entrance tube and we disign a funnel shape.For
we to set a sensor on the most narrowest of the tube.And we thought about how to reduce a
speed of a mosquito so we will use some sheet obstact a mosquito before reach the end of the
funnel by crushing the sheet so a mosquito will be slow down.And in the display section we will
use a 7-segment because it's cheap and in the status section we use an ordinary led.In architect
senior mind,when there is a counting of a mosquito we can on-off the buzzer if we turn on and
there are mosquito come in there will be a buzzer for user to feel that this machine is working.

Engineering Analysis
Strong Point
• We can show idea or vision that they are thinking and can dispute with reason.
• This week we have sure product.
Weak Point
• We work slowly because some information we never know. So we must search new.
Next Week Job

2. I will tell information about Capacitive sensor button to Product design for dimension circuit.
