| Abstract | This article presents the design and development of a relay switch (RS) to handle electrical loads up to 20A using WiFi technology. The hardware design and the implementation methodology are explained, both for the power supply and for the wireless communication that are embedded in the same small printed circuit board. In the same way, the design of the implemented firmware to operate the developed RS is shown. An ESP-12E module is used to achieve wireless communication of the RS, which can be manipulated through a web page using an MQTT protocol or via and iOS or Arduino app. The developed RS presents at least three differentiators in relation to other similar devices on the market: it can handle a higher electrical load, has a design in accordance with national and international security standards and can use different cybersecurity strategies for wireless communication with the purpose of safe and reliable use. Experimental results using a lamp and a single-phase motor as electrical loads demonstrate an excellent performance and reliability of the developed relay switch. |
