What is MQTT

Smart connected devices are emerging from the internet today. These devices are embedded with intelligence due to the development in technology. These intelligent (smart) devices are capable of interacting with humans and other smart devices, which has led to the development of “Internet of Things” (IoT). The environment can be made smart and self-aware by the direct communication between more and more devices that are part of the IoT. The IoT concept can be applied to design a smart waste management system that makes the environment clean. A smart cities project has been initiated in most developing countries. Waste management is one of the prime components of the smart city. Garbage bins can be made intelligent, so that the fill level of the bins can be sensed, and the waste can be collected. This system will minimize the time and the cost of collecting waste.
