Non-Intrusive Load Monitoring and Controlling of Home Appliances Using Bidirectional Counter

Energy conservation is a challenging issue due to increase in demands. Hence, greater interest arises in conserving electrical energy. So, electricity monitoring isessential as the concept of energy management and conservation has gained popularity. Despite of being such an essential tool, it is still done in an out-dated style. The whole process is time consuming, complex and manual with a compromise on accuracy. As a solution to this, an automated system with a high level of accuracy and proficiency using a technique called Non-Intrusive Load Monitoring(NILM) is proposed. NILM takes data from a single measuring point and disaggregates it to get energy consumption parameters of individual appliances. This project is a proposal to implement a system that can keep a track on all the home appliances and the user can obtain the energy consumption parameters of all the appliances. To implement NILM, data acquisition module based on Arduino is developed and the disaggregation is done on PROCESSING (software used for signal processing). The user can monitor the energy consumed by each individual appliance using a software and can distinguish the higher power consuming appliance. The software works as a data setter to set energy limits, which warns the user regarding the energy usage. If human presence is not detected, the active appliances will be turned off after a particular time limit which is set by the user which reduces energy consumption.
