The harvested energy is then converted into a voltage that can be used to charge devices such as mobile phones or even turn on emergency lights. In terms of its application, the system can be used to provide backup power during disaster especially during a flood or other causes of power outages. The system can also be used to charge electronic devices during outdoor activities in remote areas where electricity is inaccessible such as camping or other outdoor activities. This system can produce free electric power that can also be extremely beneficial in third world countries. The cost of the module used is also much cheaper than other existing harvesting methods such as solar panels or water turbines. Based on test data collected using IoT platform, charcoal was determined as the best material in terms of output power generated.

Malaysia is gifted with an abundance of renewable energy sources such as hydro, wind, solar, geothermal and tidal wave but most of these renewable energy resources are currently not fully utilized [1, 2]. Greater utilization of these assets will require focused efforts on different perspectives as well as exhaustive tests. Solar is one of the most used techniques that can be seen implemented in many places in Malaysia. Solar energy is one of the most popular types of renewable energy in Malaysia because of its easy implementation. Most companies and even private household in Malaysia used solar energy as their alternative source other than the typical electricity supply [3]. One thing to consider when using solar panel is it is usually expensive when it comes to maintenance, and the size of the tile is rather large and consumes a lot of space for the implementation [4, 5]. Thermoelectric generator (TEG) module is another alternative way to harvest the heat energy and convert it to electricity as what solar panel did but with a low cost [6, 7]. In this paper, a product prototype has been invented by using the TEG module, to convert the heat energy into electrical energy and channel it into AC and DC. TEG is used in this project mainly due to the cheap cost and easy maintenance. TEG module is small and doesn’t consume much space if compared to a solar tile [8]. Recently many researchers are interested with energy harvesting, which is the process of extraction energy from the external surrounding of an environment. Olsten [9] claimed to answer for little off grid-scale
