I am not using yours as your code sends the three file sequentially, but the required output sends three columns in a row, one at a time. That's why I concatenate three lines into one.
Code:
Connected to server!  
Data returned by the server:  
TEMPERATURE = 60 HUMIDITY = 40 LIGHT = 1  
Data returned by the server:  
TEMPERATURE = 59 HUMIDITY = 50 LIGHT = 2  
Data returned by the server:  
TEMPERATURE = 58 HUMIDITY = 20 LIGHT = 3

Your code sends the files one after another.
If I treat the three items (temperature, light, humidity) as a single intact record, then your output seems different from the sample output format, whereas my way seems to be what is required, except the following problems:
1)The whole dataset is output all at once, instead of individual record (3 numbers in a row);
2)The whole dataset is output in the way of 1) 30 times in total (which is exactly the total record numbers), that's what should be fixed.
Not sure if I missed some of your points. Thanks.
