Abstract

According to the Department of Environment, the higher occurrence of wildfires relates to hot and dry weather, that also received 19,099 biomass burning reports over a three-year period from January 2019 to January 2022. Based to the ministry, Malaysia often suffers a hot and dry period from the month of January to the middle of March owing to the second stage of the northeast monsoon, when rainfall absorption percentages are minimal in most locations of the nation. A drastic climate change had caused in global warming which increase the chances of human in getting heat stroke. In addition, the heat stroke will not only happen at open space but can occur inside a vehicle. However, another advantage of the heat is the existence of solar power. The solar power will be used as a recyclable power in the system through a photovoltaic chip. In this project, the applied device called exhaust fan is invented by the usage of Blynk application to add in more features of maintaining the temperature in the cabin vehicle. This exhaust fan only requires an internet connection and can be controlled from further distance. The device is then tested in a used car with the interior dimension of 3263060 cm³ starting from 1100 hours until 1600 hours. The device runs for 30 minutes after receiving a notification from the Blynk. The greatest temperature differential is seen on 1230, with a variation of 20 °C. Small differences on temperature due to cloudy weather of the day. The efficiency without exhaust fan is 12.73 % while the overall efficiency attained for all temperature, heat quantity, electric work, and power readings is just 12.93 % with differences of only 0.2%. This is a minimal percentage of efficiency, implying that the gadget can only be completely operational if the cabin dimension is anticipated to be 421913.66 cm³. However, if the quantity of fans or the placement of the device in the cabin automobile increases, the exhaust fan can be fitted to the 3263060 cm³ cabin.
