Multiple thermocouple sensors with multiple display

i'm not ee background , i'm new arduino. appreciate given advices.

i'm trying start new project related temperature monitoring. monitor temperature of 5 different rooms using 5 independent thermocouples , display values single or multiple displays. @ same times, want shows temperature difference between 2 rooms. display can such 7" tft lcd display or multiple 7-segment or multiple serial lcd (preferable large display easy monitoring). great if data can export computer using rs485. possible perform 1 arduino mega?

thanks help.

yes.

you better off using ds18b20 sensor. digital, talks english, , easy use.

a single tft screen more than  enough handle 7 sensors.

i don't know rs485 common send such data pc serial, usb cable, or bluetooth.

you biggest problem cabling or w.h.y data central arduino. may mean need few arduinos simplify communication.
