Development of a Smart Plug Controlled via a Smartphone Application Using Blynk

Abstract

The purpose of Development of a Smart Plug Controlled via a Smartphone Application Using Blynk is to 1) develop the development of the plug-in on-off device with the Bling application controlled by a smartphone 2) study the satisfaction of users of the plug-in on-off device with the Bling application controlled by a smartphone The research tools are the plug-in device, the efficiency test of the plug-in on-off device with the Bling application controlled by a smartphone, and the satisfaction questionnaire of users of the plug-in on-off device with the Bling application controlled by a smartphone, estimating the value at 5 levels. The statistics used in the research are percentage, mean, and standard deviation. The results of the study found that the development of the plug-in on-off device with the Bling application controlled by a smartphone can be used to control the opening and closing of all 4 sockets via the Bling application effectively according to the objectives. Overall, it is at a high level (=4.24, S.D.=0.48). When considering each aspect, the results are as follows: In terms of design, it is suitable for use. Overall, the satisfaction of users with the power strip set controlled via smartphone was at a high level (=4.00, S.D.=0.71). The suitability of the device size (=4.20, S.D.=0.84), ease of use and convenience of application (=4.60, S.D.=0.55), safety of use (=4.40, S.D.=0.55), and ability to be applied in practice (=4.00, S.D.=1.00) were at a high level overall.
