ABSTRACT:

Through the history, the significant amount of solid waste generated by humans was due to low population density and low levels of the exploitation of natural resources. But in today’s scenario due to increase in population there is increase in garbage. Proper disposal of garbage is necessary to make environment clean, but improper disposal of garbage leads to various issues like health problems, hazards, pollution and thus affects the environment. Pollution contains contaminants that cause instability, disorder, harm or discomfort to the ecosystem. Because of pollution the growing countries and

An effective and efficient technology is required in order to maintain a safe and green environment. The proposed method is very helpful for timely removal of waste from the garbage bins. This method involves the usage of three sensors namely infrared sensor, moisture sensor and gas sensor. The sensors are attached to the garbage bins that are placed in the public places. The infrared sensor senses the level of the garbage and when it reaches the threshold level i.e. the level of the sensor, an indication is sent to the PIC 16F877A controller that a particular garbage bin needs an attention to empty it by the worker. In the same way when the moisture sensor senses some moisture in the bin when the wet waste is deposited and the gas sensor senses some unpleasant or toxic smell from the bin an indication is sent to the PIC16F877A controller. In the transmission side the microcontroller receives the information and transmits the data using encoder and radio frequency (RF)
