IoT based Waste Segregation System using Node MCU


IoT based Waste Segregation System using Node MCU


The Internet of Things (IoT), as an expected infrastructure for the envisioned concept of a Smart City, brings new possibilities for the city manager. IoT vision introduces promising and economical solutions for massive data collection and its analysis which can be applied in many domains and so make them operate more efficiently. Normally there is one of the most challenging issues – municipal waste collection within the Smart City. To optimize the logistic procedure of waste collection. The presented solution provides a calculation of more efficient garbage-truck routes. As an output, we provide a set of simulations focused on the mentioned area. If the dustbin fills we get some alerts via the Buzzer also send the SMS to an authorized person at a particular time they didn’t respond we will intimate to the higher authorized persons.


The Smart City represents nowadays hot topic in terms of improving living conditions. Considering mainly the situation in the European Union, the EU national governments and also private companies are investing every year a significant amount of their budgets in research, development, and implementation of the concept of Smart City. The Internet of Things (IoT) is currently considered a basic communication infrastructure for smart cities, where machines communicate automatically with each other. The biggest advantage is the cooperation of many different communication technologies and devices within one functional system, where a big amount of information and data are shared and used in a secure and smart way.


In the existing system, garbage is collected by the corporation weekly once or for 2 days once. Though the garbage strikes and overflows the garbage bin and spreads over the roads and pollutes the environment which produces air pollution causes several diseases.?


  • Monitoring of garbage bins is improper
  • Proper messages cannot be delivered to the concerned department
  • The garbage bin may get filled at any time. Therefore waste gets overloaded.


This Proposed System consists of a mechanical setup that separates the waste and Manages the waste in a different type of box by using automation. In this system, we detect the dry and wet waste also, and this kind of waste we separate automatically. By having such a system in multiple places everything is monitored and controlled by a centralized node using IoT technology

Ultrasonic Sensor? Distance measurement

Humidity sensor? Moisture?


  • Monitoring of garbage bins is done in a systematic process.
  • Once the bins are filled the message will be automatically sent to the concerned department.
  • This makes the collection of garbage from filled garbage bins routinely. Also, this can avoid spilling waste from filled bins.


node dust bin



Node MCU is interfaced with the ultrasonic sensor and Moisture Sensor, so it acts as the heart of the system. The ultrasonic sensor gives the distance which is How far the waste object is present in the bin and the humidity sensor gives it is dry or wet waste. All the category of waste is separated into 2 separate bins.
