1.1 Background of the Project
KOOLBOX temperature
and humidity control system products are innovated to make it easier for users
and health professionals to use or store everything that requires a temperature
that is suitable for the things to be stored. As an example to consumers, if
they need to attend the intake of drugs such as insulin. Insulin should be
stored at an appropriate temperature that is at a temperature of 2 to 8 degrees
Celsius. If carried in a pen or vial,
it must be stored around 2 to 30 degrees Celsius. For the health department, if they want to transfer human
organs from one hospital to another, they also need a suitable temperature to
ensure that the organs are in good condition before being used for organ
recipients.
Therefore, this
project has three parts, namely, first the cooling system. In this cooling
system I use this Pelter effect can create a temperature difference by
transferring heat between two electrical junctions. When current flows through
the junction of the two conductors, heat is released at one junction and
cooling occurs. Next, the second part is to detect the temperature and humidity
in the KoolBox. To detect temperature and humidity I use the DHT22 sensor which
is a sensor that is used to detect two things at a time namely temperature and
humidity inside the KoolBox.
The last, the monitoring system. The monitoring system is divided into two parts, namely monitoring through the OLED Display module. This OLED display will be placed in the KoolBox to make it easier for users to see the temperature in the KoolBox. The second monitoring system is to use a cloud system. This in turn can make it easier for users to see the temperature and humidity only using their smartphone if they leave the KOOLBOX somewhere.
1.2 Problem Statement
I chose to
innovate this KOOLBOX project because I already have the experience of bringing
insulin pens back to the village. The journey to my village takes 4 hours of
travel to get to my house. While at the Hospital, the pharmacist only supplies
a small amount of dry ice to keep the insulin pen at a temperature suitable for
that, which can only be cooled for a short period. I did not know the
temperature of the dry ice supplied could maintain the right temperature for an
insulin pen to last for a long time and no damage.
In addition, on
the first intake of insulin pen, the hospital only supplied a transparent
plastic bag with dry ice and insulin pen. On the second intake of insulin pen,
I brought a heat-resistant bag and also an ice pack to keep the insulin pen
cool. I wondered what the temperature in the heat resistant bag is and how long
the dry ice and also the ice pack can last without damaging the insulin pen.
Next, if I open it, it may cause the temperature in the bag to drop and may
cause the insulin pen to be unsuitable for use. However, there another problem
is that the heat resistant bag is wet due to the melting process from the dry
water and ice pack placed in the bag. This makes me have to throw water or put
the bag than heat in the plastic to prevent continuous water leakage.
1.3 Objectives of the Project
It is essential to recognize the project's crucial facets as well as the project's product. As a result, it is critical to state and understand the project objective. These objectives will be discussed in this study during the project.
i.
To display the current
temperature inside the box on smart phone or device.
ii.
To ensure the insulin
vial remain effective by storing at the ideal temperature.
iii.
To ease the storage and
mobility of the insulin during travelling.
