|Title:||Temperatures sensing unit||Authors:||Kok, Pak Sum||Keywords:||DRNTU::Engineering::Electrical and electronic engineering::Electronic apparatus and materials||Issue Date:||2016||Abstract:||Water is a precious resource and undoubtedly so in Singapore’s context due to the country’s lack of natural resources and as Singapore moves towards its vision of becoming a smart city, water management is an essential problem to tackle. According PUB, showering constitutes to the greatest percentage of the entire water usage at 29% in Singapore, therefore the aim of the project is to fabricate a Water Saving System (WSS) which can be added onto any existing showering system. Due to production constrains, the idea will be proven through the use of a prototype. The WSS consists of four parts, the Temperature Sensing Unit (TSU), Analog to Digital Conversion Unit (ADCU), Programmable Logic Control Unit (PLCU) and the Hardware and Grounding Unit (HGU). In this report, the focus is on the TSU which is the ‘eyes’ of the system, providing the temperature data needed for the PLCU to make decisions. This report contains the research, improvement done on the sensors, testing data and personal work of the writer. At the end of the research and testing, the DS18B20 is deemed to be the best and most suitable sensor for use in the FYP and is also integrated with the other units which require temperature data. All the units were integrated successfully together and the whole WSS prototype is proven to work. Due to the success of the system, it was nominated and showcased successfully under the school of Electrical and Electronic Engineering’s Exhibit during NTU’s Open House 2016. Last but not least, the project also took part in Earthlink NTU’s Switch to Sustainable Solutions (SSS) Case Challenge 2016.||URI:||http://hdl.handle.net/10356/67837||Rights:||Nanyang Technological University||Fulltext Permission:||restricted||Fulltext Availability:||With Fulltext|
