Abstract

The rate of urbanisation has increased rapidly over the last several decades, necessitating the establishment of sustainable urban development plans around the world. The concept of smart cities is gaining popularity throughout the world because of today ’s technology and a deliberate approach. A smart city is incomplete without a smart waste management system, since they play an important part in keeping cities clean and hygienic, as well as providing a better public image for tourists from all over the world. Development of Automated Recycle Bin Compressor using Arduino for Smart city is designed to automatically compress when the wastes inside the bin reached a specific level and before the wastes are collected. This bin is suitable to be placed in crowded area to ensure the objectives were achieved. Normally, the wastes will be collected without any compression and that will be a waste of space. The bin is equipped with a sensor to detect the level of wastes in the bin to make the DC motor to start working and compresses the wastes. The sensor is called infrared sensor (IR sensor). When the led light emits and it reflect to the infrared receiver, the sensor starts to detect wastes. The sensor is located by the side of the bin and can be removed manually. By doing this, it can reduce the problem of excessive wastes and overflowing bin that are not managed well. A high torque and low rpm DC motor is used to make sure the wastes are compressed perfectly. This DC motor is working under battery. To support the battery, the bin used 3 Watt of solar panel to recharge the battery using a solar charger circuit to avoid the charging is interrupt. For example, when the battery is full, the circuit will cut off the charging process. The switch off button is located behind the bin and can be turn off manually if anything happens. Then the ESP8266 Wi-Fi module is placed to collect the data from the recycle bin. It is expected the result will improve the waste collection, reducing pollution, reducing the carbon that emitted by the vehicle and maximum utilization of the internal space of the bin.
