Real-Time Dustbin Using Gas Sensor, Ultrasonic Sensors, and ‎A GSM Module

Waste management has become a crucial problem to be concerned about because the amount of garbage has ‎increased. Hospitals, offices, and communities can avoid trash overflow by implementing real-time waste ‎containers. As a result, the researcher set up technology for monitoring garbage, which improves community ‎hygiene and garbage pickup efficiency. The system consists of a container, a microcontroller to manage the entire ‎process, two ultrasonic sensors to unlock the dust bin and measure the amount of garbage, a gas detector to detect ‎pollution and smoke, a servomotor to open the dust bin without touching it, and a GSM module to send messages ‎regarding the dust bin's level. The statistical indices' sensitivity, specificity, and accuracy, which are about 93.333%, ‎‎93.333%, and 94.791% sequentially for two scenarios with two rounds, are used to apply the experimental results. ‎Subsequently, numerous sensing elements could be combined with the ultrasonic sensor to achieve results that are ‎more accurate.
