CONCLUSION

64

The multichannel remote data acquisition and

analysing systems developed have been found to be ideal and

very much useful for data collection and analys~s from

remote areas where power supply is a major constraint I as

encountered in many of the environmental studies. The

remote data acquisition and storage unit developed consumes

very low power so that it is very much suitable for

operation from rechargeable batteries. The 8 bit data

resolution is found to be sufficient for the data related

to different environmental parameters measured using the

system. Use of single chip data acquisition system ADC

0816 has reduced the chip count and contributed to less

power consumption.

Future Expansion

The remote data acquisition and storage system

can easily be incorporated with audio, visual alarms to

indicate any malfunctioning of the system.

In cases where it is required, provision for

automatic control of the parameters can be incorporated.

65

The system can further be expanded incorporating

automatic remote data acquisition facility with PC based

control from the laboratory through wire or wireless link.

The processing of data can be on real-time or after storing

on mass storage devices.
