-
pollution monitoring: sensor reads O2 and PH level. the data is converted using ADC. data is transferred to CD/DVD or USB and used for analysis later
pro- doesn't forget readings, response is faster, automatic, 24/7, reading taken more frequently, safer
cons- expensive purchase and set up, reduces practical experience, expensive to have relaible back up, not work without electricity, power out
Insensitive care unit in hospitals- sensor reads- temp, heart/pulse rate etc. ADC used. data stored in comp. it compares old data and displays on screen- graph. if major changes alarm goes on.
