Waste Disposal Management System for Smart City Using LoRa

G. Saranyadevi, R. Vani and V.N. Bhargavee

The Internet of Things (IOT) is currently the most efficient system which enables different types of machine to communicate between one another. This communication becomes more reliable by the use of LoRa technology. LoRa is an abbreviation for Long Range which uses spread spectrum modulation technique. The major benefit is that these communications happen automatically where an immense amount of data are shared and used in a secure and smart way between different communication technologies. This is the emergence of the smart city and a major change is needed in the waste disposal management system. The presented solution provides an optimized logistic procedure of waste collection. In the proposed methodology, a microcontroller is connected with the ultrasonic sensor and moisture sensor, so it acts as the heart of the system. The ultrasonic sensor gives the distance that is how far the waste object is present in the bin and moisture sensor predicts whether it is dry or wet waste. These dry and wet wastes are automatically separated in two separate bins using servo motor. These sensors are embedded with LoRa Technology, which continuously monitors the fill rate of the bins. An optimized route is calculated and that is notified to the officials which enable them to empty the filled bins at a short span of time. The collected dry waste is to be recycled and can be used to make useful products.
