Development of Low Cost 3 Phases IoT Electrical Power Meter

In this paper, 3 phases of IoT electrical power meter is developed. The aim of this development is to create a 3 phases low-cost meter with IoT that can measure the true RMS value. The design of both hardware and software focuses on easy design, fewer components, uncomplicated processing, power component values, and using calculations according to numerical calculation method according to the basic theoretical principles. The dsPIC30F4011 16-bits microcontroller is used as the main microcontroller. The ESP8266 is used as the transmitting device. The information of the measurement is sent from dsPIC30F4011 to the Thinkspeak platform due to the serverless concept. After that, the information is displayed on the website via the dashboard. By comparing with the commercial product, this DIY is cheaper and has more flexible that the user can adjust the function and dash board as wish.
