Smart Sensor for Home Appliances

In this paper, a smart sensor system design for home appliances, such as refrigerator, is introduced. The proposed smart sensor system is designed to collect inner temperature and relative humidity level of the appliance along with condition of whether appliance's door is open or closed. A current sensor is also used to measure the current drawn by the appliance. To control appliance's connection to the grid a relay is attached to the system. Afterwards all sensor data is sent to a platform on which user can observe sensor values and control relay.
