Abstract:
This thesis presents the control of electrical appliances via the Internet of Things (IoT) for air conditioners. The control was programmed using NETPIE, coupled with Node-RED and MQTT Protocol communication system. it is convenient to use and responds to our evolving IT society.
From studying the characteristics of the Internet or IoT system using the NETPIE program developed in the country it can be used with a variety of broker services. Therefore, this electrical appliances control selects Node-RED to distribute the information and commands with users with client IDs and tokens of this control system. The test uses a smart circuit breaker and Raspberry Pi to transmit data and commands to the Internet using the MQTT protocol.
According to the results of testing the system by calling the electrical parameters of the smart circuit breaker 100 times, there was only 2 failures occurring when the percentage was 2%. An air conditioning control test for 1 month showed that the use of an Internet-based control system with NETPIE has a high efficiency. From the recording data, the smart circuit breaker shutdown command had only one error out of 60 times. The efficiency of the system was 98.33%, and the space in storage for air conditioners for 1 month on NETPIE was enough for collecting the basic electrical data.
