Introduction
In this article, we will explain how to create a Smart Dustbin using a few components like a 16×2 LCD, an ultrasonic sensor, a Sim800l module, a NEO-6m module, and the ESP8266 microcontroller.
This integration of hardware and software will enable us to monitor the status of the dustbin, Find out the Level of waste management, and provide real-time data for efficient collection and disposal.
