The circuit diagram with all the sensors and Arduino Uno is designed using circuito.io [24], an online IoT design platform. This website allows you to design mostly Arduino-based devices. The hardware part of the system was created on the basis of this design. A circuit diagram of the sy...
Furthermore, the authors also did the alcohol diagnosis and diabetes identification based on this platform. As an essential sensor type as well as a major power consumer of an IoT node, the gas sensor may significantly influence the lifetime of the whole system. The above-discussed ...
