FYP BRIEFING 2 (WEEK 11)

(WEEK 10)

i use sensor teemperature to detect temperature inside the box.

I put sensor temperature in the outside to easy monitor the temperature inside the box

Use LM35 to detect temperature

(WEEK (9)

Inside the box i put the fan to take out the hot air.

after that i put inside TEC in the box

and then i put aluminium to make the cold air in the box

(WEEK 8)

I use the wood to make this system easy troubleshoot and easy take out from the box if have a damage.

(WEEK 7)

when I test the TEC in the box, I  found cold but time short due to factor of the battery, at least I need a car battery but on due to the cost, I just use that requires a TTI using  15amp .

( WEEK 6)

I start by making wiring all TEC and fan. 7 TEC  be used to ensure cold stability must be properly ventilated so the heat can be cooled TEC.

if hot  the TEC is not cooled it will  damage the cold and the TEC will be damaged. because it requires a heat sink as cooling and proper flow of hot air

(WEEK 5)

when I put the TEC in the box, I found that hot air and cold air mix. so I have to remove the hot air to cold air filling the space in the box. I drill a hole so that the hot air can get out.
