A WASTE LEVEL DETECTION SYSTEM USING IOT SENSORS AND VIBRATION MOTOR

Trash is an inevitable by-product in human life. However, emptying a trash bin takes labor and time to identify and vacate at home and on the streets. To address the issue, this paper proposes a waste level detection system that can automatically measure the amount trash of a bin at a low cost. The proposed system employs the state-of-the-art Internet of Things (IoT) technology; it consists of an inexpensive mini vibration motor, acceleration and weight sensors, and IoT platform. The motor generates vibrations periodically that are captured by the accelerometer. Data with weight information is analyzed to detect fill-level of a trash bin. To this end, we employ a k-nearest neighbor algorithm. This paper develops a prototype and runs extensive experiments to evaluate accuracy performance of the proposed system. Results show that the system can measure waste level with accuracy of 75.39% on average and 94.7% on maximum.
