Waste Management System: Malaysian Model

System Implementation

Ultrasonic wireless sensor

Ultrasonic sensor measures the distance between the sensor and the waste inside the container and sends its information through the cellular network directly to the server. In the server, the data is processed and transformed into useful information. The filling percentage of the container is estimated based on the latest measurements produced by the sensor. The information is processed and the result appears on the web application. The sensor can continuously measure the fill level, and work with any type of bin materials and measure without physical contact with materials.

There are four level indicators for waste bin level:

1. Green: less than 50%

2. Yellow: less than 100% and more than 50%

3. Red: more than 100%

A typical concept for Smart Waste Management has concluded that the system will use ultrasound sensor and GSM network as tools to measure and transmit sensor data to the server. It requires a powerful, modular, easy to program open source sensor platform for the Internet of Things enabling system integrators to implement reliable Smart Cities and M2M solutions with minimum time to market.

The proposed SWMS requires more maintenance cost than the existing system. The most important issue is how to deliver to local authority with competitive price and less maintenance cost. With the current system, the implementation is only limited for apartment and condominium where the sensor device is put on top of the big garbage bin inside the apartment waste chamber. In the future, small IoT gadget for waste monitoring can be developed to put inside the waste chamber in front of each terrace house and bungalow to widen the implementation to the citizen.
