Smart Waste Bin
Project Area of Specialization Internet of ThingsProject SummaryKeeping the city clean is an ongoing task that need laborious efforts of people working on ground level emptying the garbage bins whenever they are full. The event of garbage bin getting full is not strictly dependent on time pattern instead it gets rapidly full sometimes or sometimes it require more than normal time to get full. IOT based smart bin with weight sensors is an innovative step making this process smooth and efficient. It will be able to monitor the garbage bins and inform about the level of garbage collected in the garbage bins via Android based application. For this system, ultrasonic sensors are attached to the bins to detect the garbage level and compare it with the depth of bin. In addition we have weight sensors attached below the bins, thus the system sends over internet not only the level of bins but also the weight of bins. This can help the authority to measure the weight of bins. An addition to this project will be recycling of food grade waste into compost that can further be used for gardens small plants and others and it will also be natural and cost efficient. The app will give a graphical view of the garbage bins and highlight the garbage collected in order to show the level of garbage collected. The LCD screen shows the status of the garbage level. It includes GPS so management will be able to know which bin is filled.
Project ObjectivesThe objectives of the project is to monitor and somewhat control the effect of garbage on environment and humans. Level of the garbage in the bin will be displayed using android application . Smart bin will be able to detect
- Humidity & weight
- Garbage level
- Plastic & Metal
- Automatic opening of lid
- Connecting components with android application
The project will use data collected from various sensors, store the data into secure database, and display using interactive graphs. We are going to analyses the data to develop a smart decision support system. The sensors that are required are:
DHT 11 sensors that measure the Temperature and Humidity locally based on esp32 microcontroller. Ultra sonic sensor that measures the distance to an object using ultrasonic sound waves. An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses that relay back information about an object’s proximity. High-frequency sound waves reflect from boundaries to produce distinct echo patterns.
Broker will be used to generate message which will be transmitted to worker/employee or to the admin about the level of the bin. Also GPs will be able to tell the location of bin which bin is filled.
Benefits of the Project| This project is about developing a sensor-based system to monitor and control environmental factors on pollution that can detect following |
| Current Atmospheric Temperature Humidity Moisture Weight Separation |
| The system will use sensor-readings of these parameters and automate relevant parameters for waste management, including humidity identifier, automatic opening of the bin with sense detection . |

Technical Details of Final DeliverableWe are going to deliver an “IOT based smart bin“ with attached sensors and a friendly dashboard displaying graphical visualizations.
The details of the proposed sensors are:
DHT 11 sensors that measure the Temperature and Humidity locally based on esp32 microcontroller.
Ultra-Sonic SENSOR measures the distance of a target object by emitting ultrasonic sound waves, and converts the reflected sound into an electrical signal. Weight sensors It converts a force such as tension, compression, pressure, or torque into an electrical signal that can be measured and standardized. As the force applied to the load cell increases, the electrical signal changes proportionally.
Humidity sensor the RHT03 (also known by DHT-22) is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn't require extra components so we can get to measure relative humidity and temperature. Proximity sensor will be complimentary as it will allow to detect all the metallic components and metal waste will be detected hustle free for further recycling & composting.
Dashboard:The sensors dashboard provides the user with a center point where they can view and control the connected sensors and actuators.
Some of the features that this view offer is:
- Information about the currently connected sensors/actuators. Levels of bin filled.
- A sensor/actuators property section.
- Weight of the bin filled and empty.
- Breadboard is the temporary hub of all the sensors.
- We configured the sensors in such a way that it gives us the understandable values
- All the values are then shown in form of numbers and levels in android application in labeled form.
