IOT Based Garbage Monitoring System

Internet and its applications have become an integral part of today’s human lifestyle. It has become an essential tool in every aspect. Due to the tremendous demand and necessity, researchers went beyond connecting just computers into the web. These researches led to the birth of a sensational gizmo, Internet of Things (IOT). Communication over the internet has grown from user - user interaction to device – device interactions these days. The IOT concepts were proposed years back but still it’s in the initial stage of commercial deployment. Home automation industry and transportation industries are seeing rapid growth with IOT. Yet not many articles have been published in this field of study. This paper aims in structuring a state of the art review on IOT. The technology, history and applications have been discussed briefly along with various statistics.

The following are the objectives of this work

• Waste Level detection inside the dustbin.

• Transmit the information wirelessly to concern.

• The data can be accessed anytime and from anywhere.

• The real-time data transmission and access.

• Avoids the overflows of Dustbins.

This IOT based waste management is very useful for smart cities in different aspects. This can been seen that, in cities there are different dustbins located in the different areas and dustbins get over flown many times

will provide complete details of the dustbin located in the different areas throughout the city. The concerned authority can access the information from anywhere and anytime to get the details. Accordingly they can take the decision on this immediately.

The circuit uses standard power supply comprising of a step-down transformer from 230Vto 12V and 4 diodes forming a bridge rectifier that delivers pulsating dc which is then filtered by an electrolytic capacitor of about 470µF to 1000µF. The filtered dc being unregulated, IC LM7805 is used to get 5V DC constant at its pin no 3 irrespective of input DC varying from 7V to 15V. The input dc shall be varying in the event of input ac at 230volts section varies from 160V to 270V in the ratio of the transformer primary voltage V1 to secondary voltage V2 governed by the formula V1/V2=N1/N2. As N1/N2 i.e. no. of turns in the primary to the no. of turns in the secondary remains unchanged V2 is directly proportional to V1.Thus if the transformer delivers 12V at 220V input it will give 8.72V at 160V.Similarly at 270V it will give 14.72V.Thus the dc voltage at the input of the regulator changes from about 8V to 15V because of A.C voltage variation from 160V to 270V the regulator output will remain constant at 5V. The regulated 5V DC is further filtered by a small electrolytic capacitor of 10µF for any noise so generated by the circuit. One LED is connected of this 5V point in series with a current limiting resistor of 330Ω to the ground i.e., negative voltage to indicate 5V power supply availability. The unregulated 12V

This project uses an ultrasonic sensor module comprising of 1 transmitter band 1 receiver. The transmitter can deliver 40 KHz ultrasonic sound while the maximum receiver is designed to accept only 40 KHz sound waves. The receiver ultrasonic sensor that is kept next to the transmitter shall thus be able to receive reflected 40 KHz, once the module faces any obstacle in front. Thus whenever any obstacles come ahead of the ultrasonic module it calculates the time taken from sending the signals to receiving them since time and distance are related for sound waves passing through air medium at 343.2m/sec. Upon receiving the signal MC program while executed displays the data i.e. the distance measured on a 16X2 LCD interfaced to the microcontroller in cm. In this system there are four ultrasonic sensors to detect the level of garbage in 4 bins. Each garbage bin doesn’t need to be of the same size here they can be of different size, Whenever the system starts it automatically checks the depth of empty bins, after that when the garbage start filling in that particular bin it matches the current height of the garbage to the total depth and based on that it estimates how much garbage has been filled in that particular bin and it sends it data to web system. The web system has a web page where level of garbage in bins is indicated in graphical user interface format. All 4 sensors are connected to AVR family Microcontroller which is in turn interfaced to LCD display to display the status of bins. WiFi modem is used to transmit the to the web page application and

garbage in any of the bins is reached to its maximum.

The scope for the future work is this system can be implemented with time stamp in0 which real-time clock shown to the concern person at what time dust bin is full and at what time the waste is collected from the smart dustbins.

economic garbage collection. The developed system provides improved database for garbage collection time and waste amount at each location. We analyzed the solutions currently available for the implementation of IOT. By implementing this project we will avoid over flowing of garbage from the container in residential area which is previously either loaded manually or with the help of loaders in traditional trucks. It can automatically monitor the garbage level & send the information to collection truck. The technologies which are used in the proposed system are good enough to ensure the practical and perfect for solid garbage collection process monitoring and management for green environment.
