The project aims in designing a system which is able to detect the smell of the dust in the dustbin. It also sends the SMS alert to the owner that the dust is full. It automatically clears the garbage without any help of mankind   The system makes use of a microcontroller. We use smell sensor which detects the smell of the dust in it. When it exceeds the maximum value of the smell, it sends the data to the microcontroller. Humidity can also be detected using Humidity sensor. The microcontroller gives input to the rack and pinion mechanical setup. Then the dust comes out when the motor gets actuated.       The major features of this project are:

1. Smell detection.
2. Rack and Pinion mechanism.

      The major building blocks of this project are:  

1. Regulated Power Supply.
2. PIC microcontroller.
3. Reset button
4. Crystal oscillator
5. Smell Sensor
6. Humidity Sensor
7. Rack and Pinion Setup
8. Relay
9. Limit Switches

        Software’s used:    

1. PIC C compiler for compiling and dumping code into Microcontroller
2. Express SCH for Circuit design.
