8 temperature sensors are connected(4 shown in diagram for simplicity).values of all the sensors are sent serially by uc to pc. software DAQ System take these values and show them on its front panel,and also logg them to the data base daq.mdb.we can set some parameters like set point low limit and high limit . when temperature of some sensor increases beyond set point ....the heater connected to controller(specific for data sensor) will be turned off / and on in opposite case.and high limit and low limits are for alarm.when temperature goes above high limit or below low limit the alarm will be turned on.
