“…In fact, the main contribution to the device power consumption is the data transmission phase: sending preprocessed information allows to reduce the transmission task, with a benefit for the average absorbed current. In Bassoli et al [28], a quantitative evaluation of this approach in the case of Wi-Fi protocol is reported. The data generated from the end device go directly, through the modem/router via Wi-Fi Protected Access (WPA) standard protocol, to the Internet cloud, where they are stored for subsequent sharing in a fast and efficient way.…”

Nowadays, analytical techniques are moving towards the development of smart biosensing strategies for the point-of-care accurate screening of disease biomarkers, such as human epididymis protein 4 (HE4), a recently discovered serum marker for early ovarian cancer diagnosis. In this context, the present work represents the first implementation of a competitive enzyme-labelled magneto-immunoassay exploiting a homemade IoT Wi-Fi cloud-based portable potentiostat for differential pulse voltammetry readout. The electrochemical device was specifically designed to be capable of autonomous calibration and data processing, switching between calibration, and measurement modes: in particular, firstly, a baseline estimation algorithm is applied for correct peak computation, then calibration function is built by interpolating data with a four-parameter logistic function. The calibration function parameters are stored on the cloud for inverse prediction to determine the concentration of unknown samples. Interpolation function calibration and concentration evaluation are performed directly on-board, thus reducing the power consumption. The analytical device was validated in human serum, demonstrating good sensing performance for analysis of HE4 with detection and quantitation limits in human serum of 3.5 and 29.2 pM, respectively, reaching the sensitivity that is required for diagnostic purposes, with high potential for applications as portable and smart diagnostic tool for point-of-care testing.

“…These devices are connected to physical items, usually called "things," such as home appliances, vehicles, buildings, and wearable objects. The IoT paradigm is applied in several applications, including transportation and industrial sectors [2][3][4][5][6][7][8], allowing users to monitor and manage complex systems in a simple way. However, IoT represents a technological challenge in several respects, specifically hardware [9] and telecommunication aspects [2,10].…”

In this paper, an overview of the research challenges in measurements for the design of Internet of Things (IoT) systems is proposed. To this end, a general architecture of an IoT system is presented, which is specialized according to two key requirements: the power supply capabilities of the infrastructure and the time delay constraints of the application. Guidelines for the design of an IoT system are summarized, and the measurement needs are highlighted. A review of the research contributions is given concerning three main measurement topics: (i) energy-aware data acquisition systems, (ii) localization of mobile IoT nodes, and (iii) precise synchronization protocols.

As technological advancement in recent years is bringing ease to our everyday life, smart home systems based on wireless networks and sensors are rapidly gaining importance. Research on microcontroller controller smart home systems has become popular due to its low cost and reliability. However, appliance switching capacity of microcontroller is quite low which limits the widespread use of such sort of systems. This paper introduces an external appliance switching circuit for microcontroller controller automated home which has the ability to control 208 appliances. This large appliance switching capability has been obtained by demultiplexing digital signals obtained from microcontroller board using a complex array of 4 to 16 line decoders. The proposed appliance switching circuit can be implemented with 60-70% less wiring cost in real time compared to the typical wiring technique in microcontroller controlled smart homes. Also, hardware implementation expenditure in this research has been reduced significantly compared to the existing designs. Moreover, the issue associated with existing microcontroller appliance switching scheme in case of incorporating manual switch has been solved. The proposed circuit is incorporated with a smart phone application by which the user sends commands to the microcontroller board using Bluetooth as the medium of wireless transfer. The proposed microcontroller controlled smart home system with external appliance switching circuit is quite cheaper than the existing systems which allows consumers to afford smart living with limited budget. Due to reduction of implementation cost and solution of major technical design issues incorporated with the existing microcontroller-based system been solved in this research work, microcontroller based smart home systems is expected to become a potential product in the market in near future.
