AB The energy supply of office buildings and smart homes is a key issue in the globalenergy system. The growing use of microelectronics-based technology achieves new devices fora more comfortable life and wider use of electronic office equipment. On the one hand, theseapplications incorporate more and more sensitive electronic devices which are potentially affected byany external electrical transient. On the other hand, the existing electrical loads, which generally useelectronic power systems (such as different types of battery chargers, ballasts, inverters, switchingpower supplies, etc.), generate different kinds of transients in their own electrical internal network.Moreover, improvements in the information of the state of the mains alternating current (AC) powerline allows risk evaluation of any disturbance caused to permanently connected electronic equipment,such as computers, appliances, home security systems, phones, TVs, etc. For this reason, it isnowadays more important to introduce monitoring solutions into the electrical network to measurethe level of power quality so that it can protect itself when necessary. This article describes a smalland compact detector using a low-cost microcontroller and a very simple direct acquiring circuit.In addition; it analyzes different methods to implement various power quality (PQ) surveillancealgorithms that can be implemented in this proposed minimum hardware platform. Hence; it ispossible to achieve cheap and low-power monitoring devices that can become nodes of a wirelesssensor network (WSN). The work shows that using a small computational effort; reasonable executionspeed; and acceptable reliability; this solution can be used to detect a variety of large disturbancephenomena and spread the respective failure report through a 433 MHz or 2.4 GHz radio transmitter.Therefore, this work can easily be extended to the Internet of Things (IoT) paradigm. Simultaneously, asoftware application (PulsAC) has been developed to monitor the microcontroller’s real-time progressand detection capability. Moreover, this high-level code (C++ language), allows us to test and debugthe different utilized algorithms that will be later run by the microcontroller unit. These tests havebeen performed with real signals introduced by a function generator and superimposed on the trueAC sine wave
