The Internet of Things (IoT) has recently become a dominating technology which allows different "things" to communicate through the Internet and understand each other. IoT uses Artificial Intelligence techniques to process data gathered by different sensors and act accordingly. The world is now moving towards employing IoT in different disciplines such as manufacturing, agriculture, education, commercialization, smart homes, auto cars, and almost everywhere. The explosive growth of IoT is changing our world and the rapid drop in price for typical IoT components is allowing people to innovate new designs and products at home. Thus in this paper, we present the topic of "sensing" with liquids, weather, soil, smoke, and distance measures. GPS-based location acquisition is also part of several applications presented here. Sensors are used for data acquisition and IoT devices are used for data exchange through a web server. Different sensors are introduced and linked with in-house, easy-to-customise and low-price IoT systems connected to mobile applications. Our paper demonstrates that IoT is powerful and ubiquitous and can be implemented in large-scale applications including managing liquids, controlling the stocks, building alarm systems, smart home control, smart irrigation, and alike.
