Making overheating alarm system

Hi genius. I am making overheating mail alarm system. I use thermocouple wire. For CJC, I will just input 20℃. And I use Arduino uno, Ethernet Shield and RJ45 for supply energy and sending data. To give IP, I choose W5100. Of course, I will make op amp for multiply input signal from thermocouple. And I will use low pass filter for remove noise.

Arduino uno, Ethernet Shield, RJ45, W5100, Op amp, low pass filter, thermocouple.

Is these perfect to make mail alarm system.

Perfect? Probably not. Sufficient? Probably.
