[email protected] method of connecting the objects or things through wireless connectivity, Internet called Internet Of Things. Nowadays avariety of tasks are based on IOT. Cities in the world are becoming smarter by implementing the things around using IOT. Thisis a new trend in technology. Smart cities include obstacle tracking, object sensing, traffic control, tracking of our activities,examining the baby, monitoring home lights and so on. One of the objectives of smart cities is keeping the environment cleanand neat But this Smart cities aim is not fulfilled without the waste management system. Hence the paper “IOT Based smart Binfor Smart Cities” has been developed. Bin management is one of the major applications of IoT. Here sensors are connected to theall the bins in different areas. It senses the level of garbage in the bin. When it reaches threshold a message is sent via GSM tothe concerned person to clean it as soon as possible.Keywords: IR sensors, Microcontroller , GSM Modem,1. INTRODUCTIONGarbage management is that the assorting, transportinggarbage, processing, reusing or eliminating and monitoringgarbage materials. Garbage management is very crucial and ithas become one of the major issues due to high populationdensity. To reduce the impact of garbage, MunicipalCorporation has developed an efficient garbage managementsystem. In India, waste generated per capita ranges from 200gto 500g. Many organizations have estimated that in India 1.3 to1.5 pounds of waste is generated for a person. The efficiency ofcollecting the garbage is poor in Indian cities compared to othercountries. Thus, Indian Government is struggling to manage thegarbage. Issues with respect to the disposal have becomechallenging with growth in population. Poor garbage collectionand improper transportation facility are answerable for theearnings of garbage at all spots and points of the city. Due tothese unavailable facilities, municipal garbage management isgetting critical. Improper garbage management further leads toincurable diseases to living organisms. Thus to avoid wasteoverflow “Smart Management of Garbage” has been proposed.components can detect it. It consists of IR transmitter and IRreceiver. Both analog and digital output is produced by IRsensor. This sensor produces the output a logic 1? at thedigital output when it senses the object and a logic 0? when itdoesn’t sense any object. IR transmitter consists of LED whichsends the IR beam. To receive this beam IR receiver,TSOP1738 is used. The output of TSOP1738 directlyconnected to the microcontroller and it has high immunityagainst ambient light and other electrical disturbances. It isable to transfer data up to 2400 bits per second. It needs thepower supply of 5V. IC555 is used to design the IRtransmitter of 38 KHz.2. SYSTEM DESCRIPTIONFor the garbage detection, weight sensor can be used. It givesthe weight of the garbage in the Dustbin. But it doesn’tprovide any information about the level of the garbage in thedustbin. Hence author used IR sensor for garbage detection.Infrared sensor (IR sensor) is used which is a multipurposesensor, which can detect the level of garbage. IR sensor emitsthe light, which is invisible to the naked eye but the electronicFig. 1. Arduino Uno BoardNational Conference on Recent Trends in Electronics,Communication & Computing (NCRTECC-2018) 2Microcontroller is a small computer on a single integratedCircuit containing a processor core, memory, andProgrammable input/output peripherals. It is used inAutomaticallycontrolledproductsanddevices.Microcontroller Atmel328 is used in this work. Figure 1shows the Arduino Uno board used for programming whichincludesMicrocontrollerAtmel328.This Microcontroller is a high-performance 8-bit AVR RISC-based microcontroller combines 32KB ISP flash memory withread-while-write capabilities, 1KB EEPROM, 2KB SRAM, 23general purposes I/O lines, 32 general purpose workingregisters, three flexible timer/counters with compare modes,SPI serial port, 6-channel 10-bit A/D converterWireless communication can be achieved using manydevices. Those devices are Zigbee, GSM, etc. In this project,GSM is used. Zigbee can also be used but the disadvantagewith it is its short range, less complexity and the speed of datais less. Hence author uses GS modem because it is simple touse and it’s less cost. GSM modem is a unique type of wirelessmodem, accepts a SIM card and it operates similarly to amobile phone with its own specific mobile.A GSM modemcan be an external device or a PC Card / PCMCIA Card. Anexternal GSM modem is connected to a computer through aserial cable or a USB cable. When a GSM modem is connectedto a computer, this allows the computer to communicate overthe mobile network. While these GSM modems are mostfrequently used to provide mobile internet connectivity, manyof them can also be used for sending and receiving SMS andMMS message. GSM Modem sends and receives data throughradio waves. In this project, GSM 900 modem is used to sendthe messages which are shown in figure 2. It consists of aGSM/GPRS modem with standard communication interfaceslike RS-232 (Serial Port), USB, so that it can be easilyconnected to the other devices. The power supply circuit isalso built in the module that can be turned ON by using asuitable adaptor.Fig. 2. GSM Modem3. BLOCK DIAGRAMA. TransmitterFigure 3 shows the block diagram of transmitter section. Thelevel detector consists of IR sensors which are used to detectthe level of the garbage in the dustbin. The output of the leveldetector is given to microcontroller. Four IR sensors are used toindicate the different levels of the amount of the garbagecollected in the dustbin which is placed in the public area. Whenthe dustbin is filled up to the highest level, the output of fourthIR receiver becomes active low. This output is given tomicrocontroller to send the message to the Control room viaGSM module as shown in figure 5.Fig.3 Transmitter SectionB. Receiver sectionFigure 4 shows the block diagram of receiver section. Atreceiver, the control room is present where all the activities aremanaged. The number of the control room depends on thedustbins present in the area. The person sitting in the controlroom monitors the entire system. A GSM Module is connectedto the computer of the control room through the microcontroller.The same GSM Module is used to send the message to thecontractor for cleaning the dustbin. GUI is developed usingMATLAB software. This GUI will be displayed on thecomputer screen in the control room to display the status of thegarbage level in the dustbin as shown in figure 6.Fig.4 Receiver sectionNational Conference on Recent Trends in Electronics,Communication & Computing (NCRTECC-2018) 34. FLOW CHARTThe flowchart of the project is shown in Figure 5. It literallyprovides the idea for this project. The IR sensor arrangementacts as a level detector.The output of the level detector is givento the microcontroller (as shown in figure 3). The ATcommands are used to facilitate the messaging service throughthe GSM Module. This program is burned in themicrocontroller with the help of Arduino software (IDE)version1.6.1. These messages consist of information ofgarbage levels of respective dustbins. Depending on theinformation sent to control room, the authority informs theconcerned person of the respective area about garbage level.Then the concerned person makes sure that the garbage of thatparticular area is collected by sending the cleaning vehicles.collection viz. location of the dustbin, status of the dustbin,date & time of garbage collection.6. C ONCLUSIONpapershowstheimplementationofThissmart garbage management system using IR sensor,microcontroller, and GSM module. This system assures thecleaning of dustbins soon when the garbage level reachesits maximum. If the dustbin is not cleaned at a specifictime, then the record is sent to the higher authority whocan take appropriate action against the concerned contractor.This system also helps to work or suggestapplications and extensions. Monitor the fake reports andhence can reduce the corruption in the overallmanagement system. This reduces the total number oftrips of garbage collection vehicle and hence reduce theoverall expenditure associated with the garbage collection. Itultimate helps to keep cleanness in the society. Therefore, thesmart garbage management system makes the garbagecollection more efficient.ACKNOWLEDGMENTOur special thanks go to our guide Prof. Rajput Swati andcollege professors for guiding us for representing our ideathrough this paper and people who have willingly helped outwith their abilities.REFERENCES1 Zembedded, “GSM modem interfacing with 8051 forSMS”.2 Hindustan Embedded System, “City Garbage collectionindicator using RF (ZigBee) and GSM technology”.3 S.
