Especially in places with diverse temperature, one often struggles to have water in an ideal temperature; it is either too cold or sometimes too warm. This study experimented a possible way to help outdoor enthusiasts to consume safe drinking water in their preferred ideal temperature by having a smart water bottle with peltier module which enables a dual feature that allows to either warm or cool the water, along with an auto filtration device for purifying the water if some bad agents are found in the water. This paper presents the system architecture of the smart bottle and the results derived from the preliminary testing of the mock up prototype device. .

INTRODUCTION With the passage of time, however, comes the necessity to upgrade and develop new technologies. While travelling, hiking, camping or trekking people consume both warm and cold water depending on the climatic temperature. To consume a hot liquid nowadays, we must either carry it in a thermos, purchase it fresh, or have access to a heating source and vice versa for having cold water. [1]. The proposed idea is to have a smart water bottle which has temperature sensors where it can sense the water temperature inside the bottle and with the help of peltier module it can cool down or warm up the water to a desired temperature. This desired temperature can be preset manually and the automatically. As an additional accessory we proposed to have a portable water filtration device that can be used as and when required in places where clean hygienic water availability is critical. It might be beneficial or rather necessary to disinfect the water to kill waterborne germs before using it. II. PROBLEM IDENTIFICATION Exposure to both very warm and cold temperatures could be harmful for certain health conditions and not having to drink water in a preferable temperature level might make a person fall sick. Purchasing hot water fresh or cold water is not always a viable option due to rising costs, a lack
