Abstract- – This paper presents the simple and low-cost design of an IOT based automatic power factor correction (APFC) system for single-phase domestic loads. The proposed design uses relays to switch the capacitor banks in order to correct the power factor of inductive loads. An Arduino board controls the switching of relays based capacitor re-actor bank depending on power factor measured. The Arduino is programmed to non-stop monitor and calculate the power factor of the connecting load by sensing the signal from CT, PT and Zero Cross Detectors (ZCDs), and keep the power factor of the load above the reference value (0.95) by appropriately energizing the capacitors in parallel to the connecting load through relays switching so as to correct power factor close to unity. The value of power factor before and after improvement is displayed on LCD. The hardware prototype of the proposed APFC design is also developed to validate its operation. The satisfactory and acceptable results of the APFC system test have con-firmed that the suggested design yields a reliable output and can be further used in any single-phase practical application to ensure the power factor close to unity. This setup improves power factor up to 0.99. Power factor can be monitored on thing speak web-site transmitted via nodemcu module.
