Quality of water can be determined by measuring water resistance values. The resistance parameter is used as a reference to determine water quality based on physical properties where the minimum value for the clean water category is 333.33 Ω. Therefore we need a measuring device to check the value of water resistance. A voltage divider is a simple...

We propose the compact PRESENT on embedded processors. To obtain high-performance, PRESENT operations, including an add-round-key, a substitute layer and permutation layer operations are efficiently implemented on target embedded processors. Novel PRESENT implementations support the Electronic Code Book (ECB) and Counter (CTR). The implementation o...
This paper presents a hardware and software of an electrooculogram (EOG) acquisition system based on ATmega AVR microcontroller for the acquisition of vertical and horizontal eye movements. The presented system is used to acquire a dataset of eye movements for volunteers. This system gives two channels representing vertical and horizontal EOG signa...
Today, smart city approaches are considered as a key to solving the problems facing metropolises. However, using this approach, the costs of investment, operation, and maintenance of infrastructure in cities will be significantly reduced. In this study, a system for intelligent temperature control of urban equipment (electrical panels) and fire pre...
