I need to know if there is a sensor that mesure pH and ORP, I have already googled about this type of sensor but i found only AtlasScientific that commercialise this kind of sensor



Yes there are lots. You might try search for "Arduino PH Sensor" and "Arduino ORP sensor" you'll get a lot more hits for Arduino than ESP8226. This might be useful: http://www.instructables.com/id/ORP-pH-Temperature-Data-Logger/?ALLSTEPS
