3.3 SYSTEM OVERVIEW
3.3.1 INFRARED SENSORS IR Sensors work by using a specific light sensor to detect a select light wavelength in the Infra-Red (IR) spectrum. By using an LED which produces light at the same wavelength as what the sensor is looking for, you can look at the intensity of the received light. When an object is close to the sensor, the light from the LED bounces off the object and into the light sensor. This results in a large jump in the intensity, which we already know can be detected using a threshold.

3.3.2 USB DONGLE A dongle - also called an internet dongle - is a small USB device that is used to access the internet. It can be referred to as a dongle, …show more content…
This USB dongle is connected to USB port of Raspberry Pi Model B+ kit for its proper functioning.

3.3.3 RASPBERRY PI MODEL B+ KIT The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse. The Raspberry Pi Model B+ kit is connected to the IR sensors so as to record its output. To achieve this purpose one of the wires soldered to LED is connected to GPIO pin in the kit and the other pin is connected to Ground pin of the kit.

LIRC which stands for Linux Infrared Remote Control in the Raspberry PI Model B+ kit helps in achieving this purpose.

PROPOSED MERITS
Needs no man power for operation purposes. Even if the common public neglect to report to the municipal regarding waste collection, this automated system monitors the waste and informs the waste collection department on its own.

FUTURE ENHANCEMENTS
The size of solar panels used for power optimization is the future enhancement of this paper.

CONCLUSION
This paper describes a model using an automated system which reduces manual labor. Unlike the traditional smart bins manufactured by green tech life it does not involve manual labor. Use of internet has become popular. Hence we conclude that this way of employing different technologies for collecting waste will be productive for the public and helps in maintaining a tidy environment as well. In current scenario nearly 1 lakh rupees is invested for setting up of a single garbage bin whereas the smart bins setup does not even sum to one tenth of its total cost. Though garbage bin is present a tidy environment cannot be guaranteed because there are possibilities of the bins to overwhelm out of waste. In the case of smart bins this issue is overcome due to
