A Smell Sensor based Improved Waste Management System for Green and Smart Cities

IoT is crucial for smart city applications to improve. The typical waste management method starts with garbage generated by municipal residents and deposited in garbage cans at the source. Outdoor containers are not kept up with by municipalities or trash management businesses, production it incredible to know when they need to be cleaned or when they are jam-packed. The author presents a smart city based IoT-allowed solid waste management system in this paper. Its goal is to break beyond the limits of existing waste management techniques. PBLMU and HBLMU end sensor nodes are used to pathway trash bins in residential zones and public area, respectively, in the proposed design. Using an intuitive Graphical User Interface, the garbage collection authority can view and also analyse the unfilled status of every waste bin (GUI). Multiple dustbins can be found throughout the city, university, or home in this paper. These garbage cans are equipped with a sensor that allows them to track their level and weight. Every rubbish bin in the city will be equipped with PBLMU and HBLMU, making it easy to determine which bin is full. The gadget will broadcast the reading along with the Lora WAN Gateway when the bin’s level and weight approach the threshold limit. Harmless chemicals are put to the smell sensor, which is used to detect the rotting smell, in order to avoid the decaying scent around the bin.
