Capturing data for both operating machinery and its environment is of priority in most industries especially heavy industries. Some industries need to continuously and simultaneously monitor physical quantities such as temperature, pressure and speed of various parts of different equipment used in other to maintain and improve the quality of products and the efficiency of the process. The common and oldest system used to gather data is the wired sensor systems. This paper looks at wireless sensor technologies that can be used in heavy industries to capture much-needed data for analysis and logging. A few of the technologies were looked at. Challenges and advantages of each were highlighted. It was concluded that ZigBee communication technology has a better chance in the industrial environment.

Increase in the demand for consumer electrical and electronics equipment which is driven in part by the rate of technological advancements invariably gives rise to more products requiring the use of circuit boards. This paper analyses the manufacturing process of printed circuit board (PCB), disposal of waste PCBs at the end-of-life and how it affects the environments. Legislation on production and waste disposal was also be examined with specific interest in how these laws affect production and sustainable alternative ways to manufacture PCBs. Research into new types of environmentally friendly printed circuit boards, with particular interest in the recycle and re-use of the boards and components respectively and the life cycle assessments (LCA) which analyses the entire life phase of PCBs. In conclusion, the paper confirms the possibility of developing an environmentally friendly circuit board as an alternative to PCB.
