Development a prototype of the smart bin for supporting solid waste management at source

Abstract

Develop a prototype of the smart bin for supporting solid waste management at the source. The objective is to develop the functionality of the smart bin to meet the requirements of users. A body design of the smart bin prototype made from plastic with a lid, size 25 cm. x 36 cm. x 48 cm., the total volume of the smart bin was 31.5 kg, and using ARM STM32F4 series micro controller to control the functions of the smart bin. There is a sensor to measure the temperature and humidity. Ultrasonic level sensor Infrared distance measuring sensor and weight sensor with load cell data display controlling the opening and closing of the smart bin by servo motor. A Smart bin prototype can show the amount of waste. Moreover, the level of waste and the weight of the waste inside were showed. The smart bin was showed relative temperature and humidity values inside a bin. The optimum distance to the reflective object of the sensor for opening and closing the smart bin was in the range of 20-50 cm. The Smart bin lid provided approximately 7-9 seconds to maintain the status to lid open, representing an average time of 7.4±0.9 seconds. This research will help promote waste management at the source and effectively benefits to solve the problem of waste accumulation in place.
