9. Data Processing Design Examples Divide the present temp. value of the first thermocouple module by 10 so as to change the unit into 1 ℃ . The omitted data processing of module 2, 3, 4 is same as module 1 and module 5. Divide the present temp. value of the 5th thermocouple module by 10 so as to change the unit into 1 ℃ . X1 Counting the amount of rooms whose temperature is 25 and searching the room number of the highest and lowest temp. ℃ Program Description: z Acquired temperature data and search result of 20 rooms:
