pH, TDS\EC, ORP, temperature - metr

I want to build a device for measuring pH, TDS/Ec, ORP and temperature using Arduino. Can you help me with a diagram and sketch? Perhaps you have already seen the finished product somewhere? I will be very glad if you help me

There are Fritzing parts for PH and TDS (I have no idea if it also does Ec), I have no idea what ORP is and there are a variety of temperature sensors available. In general a google search of the form "fritzing part part number: (where part number is the part you need) will find Fritzing parts that people have made. Good luck.


this is the orp sensor, can you do it please

This part should do what you want.
