Advise for 5 sensors on one Arduino

I would like to build a small arduino that will collect measures from sensors and that will be available on the Internet.

I should need:
3 temp sensor + humidity sensor
1 Electrical conductivity sensor
1 pH sensor

After going through the webshop and couple of articles, I think these are the articles I need:

Romeo - an Arduino Robot Control Board with Motor Driver
Ethernet Shield for Arduino - W5200
Gravity: Analog pH Sensor / Meter Pro Kit For Arduino
Gravity: Analog Electrical Conductivity Sensor / Meter For Arduino
Gravity:SHT1x Humidity and Temperature Sensor

Is this correct? Is the arduino romeo not oversized for my project? Is there any advice you can give me?

Thanks very much! :D

All the sensors and mainboard you choose is good to use, but if you put the pH sensor, EC sensor and humidity/temperature sensor in the same tank for example, there will be signal inference between each other, so the analog signal isolator is recommended
