The IoT application covers smart and healthy environments in various domains but not limited such as: agriculture, building, city, culture and tourism, emergency lifestyle, environment and energy, factory, supply chain, healthcare, retail, transportation, user interaction, etc. There is plenty of documented literature available in the internet and digital space (database) on IoT from knowhow, hands-on to its implementation and testing using both proprietary and open-source tools. However due to lack of availability of structured and complete set of instructions in the internet space, with special attention to several project activities including software and hardware development phases is exceptionally challenging to rapidly prototype and test an IoT enabled sensor device in timely manner. The objective of this paper is to demonstrate a project and document the complete structured set of instructions to research, design, rapid prototype and test a general purpose IoT enabled sensor device using open-source tools.

INTRODUCTION The IoT concept was coined by a member of the Radio Frequency Identification (RFID) development community in 1999, and it has recently become more relevant to the practical world largely because of the growth of mobile devices, embedded and ubiquitous communication, cloud computing and data analytics. Internet of things is an internet of three things: (1). People to people, (2) People to machine /things, (3) Things /machine to things /machine, Interacting through internet .[1]. The IoT application covers smart and healthy environments in various domains but not limited such as: agriculture, building, city, culture and tourism, emergency lifestyle, environment and energy, factory, supply chain, healthcare, retail, transportation, user interaction, etc. In this context, it is possible that the level of diversity will be scaled to a number a manageable connectivity technology that address the needs of the IoT applications, are adopted by the market, they have already proved to be serviceable and are supported by a strong technology alliance [2] . Examples of standards in these categories include wired and wireless technologies like Ethernet, WI-FI, Bluetooth, ZigBee, GSM, and GPRS. The term IoT (Internet of Things) has recently become more relevant to the practical world largely because of the augmentation of mobile devices, embedded and ubiquitous
