Smart Trash can with User Photo Capture Using Internet of Things

The growing environmental pollution and the lack of recycling awareness have forced governments to establish policies for waste control. The technology is used to apply these policies as a support tool. In this work, smart trash can was implemented using IoT through an ESP32 and Esp32CAM board linked to the ThingSpeak platform to communicate the stations. Since the charge is by weight, the goal is to encourage people to recycle as much garbage and pay less. This system has a mobile application to start it up and visualize the data obtained. The system captures a photo of the user, senses the weight of the garbage, and determines the value to pay. In addition, an OLED screen is incorporated into the smart trash can to display the weight and value to be paid. The data collected demonstrates the system's proper functioning, and the usability evaluation indicates a rating of 76.5%, which is satisfactory for this proposal.
