Abstract

An inefficient home appliance is difficult to be detected by the consumers. The consumers are often to pay overcharged electricity bills due to the power overconsuming household electrical appliance. Therefore, this project describes on the development of a low-cost device to monitor the energy consumption with the addition of IoT technology which is named as Integrated Wi-Fi Socket Outlet with Power Consumption Reader (WISOC). The device could display three types of information on its screen which are the power consumption (W), the energy consumption (Wh) and the cost of electricity (RM). The device also can transfer its data to the internet by using Blynk application software and display it to an IoT compatible devices such as smartphone and computers. There are ten household appliances that were tested and each with different time taken range. Calibration is needed to improve the accuracy by calibrating the current to 0A with no load. The accuracy of measurements using WISOC are determine using true rms clamp meter by comparing the current measured by WISOC with the current measured by true rms clamp meter and small difference will deduced that the device is accurate. As for detection of inefficient appliances, the reading of power measured by WISOC is compared with the power rated of appliances and if the reading of power measured by WISOC is larger than the power rated of appliances, the appliances are deemed to be inefficient. All the results are then tabulated in tables and graphs. Furthermore, this project still has the room for improvement in terms of accuracy of measurement, functionality and potential to be marketed.
