SMART GARBAGE MONITORING SYSTEM USING IOT Y.Himanth1, B.V.Pavan Kumar2, M.Lalitha Bhavani 3 1,2,3Asst.Professor, ECE Department, SASI Institute of Technology & Engineering, Tadepalligudem, India Abstract Helps in maintaining the surrounding of In the recent years, there was a rapid growth dustbins clean. in population which leads to more waste The statistics can be used to estimate area disposal. So, a proper waste management wise quantity of waste which in turn used system is necessary to avoid spreading some to rank areas. deadly diseases. But due to lack of resources, In our system, the Smart dust bins are ineffective groundwork, some waste is not connected to the internet to get the real time collected which poses serious health hazard to information of the smart dustbins. These the surrounding environment. The dustbins are interfaced with Arduino based government of India announced smart cities system with ultrasonic sensors and weight and the key to smart cities is cleanliness. In sensors and Node MCU. Where the ultrasonic support of clean city we design a dustbin sensor detects the level of the dust in dustbin and which can interact with the cloud (free cloud sends the signals to Node MCU the same signal for demonstration) and push its filling percent is encoded and send to the application and it is at regular intervals (say every 1 hour or its received. The data has been received, analyzed status set to full). If the status of the dustbin is and processed in the database, which displays the filled, a message is pushed to the municipal status of the Garbage in the dustbin on the person who is responsible to empty the bin. application of authorized person system through The filling percent monitored by weight web application. The concerned authority get sensor and ultrasonic sensor continuously. alert about dustbin is full and informs person The status of the bin set to full when either the whoever is responsible for collecting garbage threshold weight reached (may be some space from the particular areas. The garbage trucks available in the bin) or it is filled up to a collect the garbage from the completely full threshold level (may be the weight less than dustbin and dispose. the threshold) and by using analysis of statistics to estimate area wise quantity of II METHODOLOGY waste which in turn used to rank areas which The whole proposal contains the following helpful in cities clean. modules INDEX TERMS: Internet of things (IOT) Collecting data from sensors. Pushing the statistics onto cloud at specified intervals. I. INTRODUCTION Accessing statistical data using Owing to the characteristics and merits of IoT web/mobile application. services, waste management has also become a 2.1 Collecting data from sensors: significant issue in academia, industry, and Ultrasonic and weight Sensors to be government as major IoT application fields. placed on garbage bins. Data is collected from Our Aim towards the designed proposal are the ultrasonic sensor information and weight Dustbins can be emptied before they sensor information. The ultrasonic sensor sends filled completely. triggering pulses on the garbage and according to Save the time and efforts to view overall it receives an echo signal to calculate level. The the process. weight sensor converts the load into an electrical ISSN (PRINT): 2393-8374, (ONLINE): 2394-0697, VOLUME-5, ISSUE-4, 2018 55 INTERNATIONAL JOURNAL OF CURRENT ENGINEERING AND SCIENTIFIC RESEARCH (IJCESR) signal which is given to A/D converter for the weight information 2.2 Pushing the statistics onto cloud at Ultrasonic specified intervals: Levels and sensor The whole data is collected and is pushed into Wi-Fi weight data group by ID,Area the IOT cloud platform and the statistics are Node MCU observed. This data is given to the ARDUINO cloud database and it is given at specific UNO Cloud data intervals. base 2.3 Accessing statistical data using web/mobile application: Weight Alert as a Web Each bin is given a tag id and each id information sensor message system is in the web application developed. In the web TAG ID :xxxx application the area cards are displayed where the status of each bins in that area is determined. Fig 3.2: Detailed Design From there it can be known the bin levels of IV SENSORS different areas and if the bin is filled then an alert Ultrasonic sensor: can be sent to the municipal driver. An Ultrasonic sensor is a device that can measure the distance to an object by using sound waves. It measures distance by sending out a III.DETAILED DESIGN sound wave at a specific frequency and listening The system is designed in such a way that for that sound wave to bounce back. It is it avoids the overflow of the dustbin and keeps important to understand that some objects might the environment dust free and pollution free. not be detected by a ultrasonic sensor. Making the environment clean and tidy. By sending alerts to the municipal department with help of a microcontroller linked with a web server using IoT.

Fig 3.1: proposed block diagram Load cell is transducer which transforms force It also provides the verification process after or pressure into electrical output. Magnitude of cleaning the dustbin. The level of the dustbin is this electrical output is directly proportion to the calculated by measuring the distance of the force being applied. Load cells have strain nearest obstacle using an ultrasonic sensor. Here gauge, which deforms when pressure is applied not only the level by the weight also we can on it. Now the electrical signals generated by determine the filling of the bin as in bulk it Load cell is in few millivolts, so they need to be cannot be emptied. NodeMCU is used as the Wi- further amplify by some amplifier and hence Fi module to read the data from the ultrasonic HX711 Weighing Sensor comes into sensor and the Arduino is interfaced with weight picture. HX711Weighing Sensor Module has sensor and through serial transmission the data is HX711 chip, which is a 24 high precision A/D sent to the NodeMCU. It is programmed to send converter (Analog to digital converter). so an alert to the Thing Speak web server once the HX711 module amplifies the low electric garbage reaches a certain distance and weight output of Load cells and then this amplified & ISSN (PRINT): 2393-8374, (ONLINE): 2394-0697, VOLUME-5, ISSUE-4, 2018 56 INTERNATIONAL JOURNAL OF CURRENT ENGINEERING AND SCIENTIFIC RESEARCH (IJCESR) digitally converted signal is fed into the Arduino gives us a channel feed in which the data can be to derive the weight. extracted and the data used in the web application for analyzing and act according to it that is we sending the message.
