There were a few goals that were not achieved during the design process. One such unfulfilled goal was to verify the correct operation of all the blocks integrated into one system. Currently the system is being tested using a wave generator in place of a crystal to verify that the system will indeed work, but has not yet been verified. Another goal that was not achieved was the integration of all the combinational logic onto a single programmable chip. In the future, it would be ideal to place all the logic onto a single FPGA or PROM of some type.

There were also a few new ideas that may enhance the functionality and operation of the system. First off, it would be beneficial to be able to differentiate between alarm signals coming from the system to identify where in the building the fire originated. Along those same lines, the development of a central monitoring station would provide a graphical display of where the fires are being detected in the system. Finally, by gaining better understanding of the UART interface, it will be possible to develop combinational logic on the same programmable chip to deal with flow control and eliminate the need for the external UART controller. If all the logic functionality is integrated on a single integrated circuit, the cost of the smoke detector will be significantly reduced. If these devices are to be produced in high volume, then the control logic as well as Bluetooth module can be integrated onto a single chip, Bluetooth-enabled, smoke detection system.
