3.3 Volt comparability of analogue sensors
![userHead](https://dfimg.dfrobot.com/dfPortrait2.png)
I have hooked up the Analog EC sensor to a 3.3 v micro controller, and it seems to be working. Your website says that it's a 5V item. Am I using it outside of spec?
What about other water sensors, so Analog pH Meter Pro, Analog ORP, etc? How do I know which ones are 3.3 V compatible?

I know it says 5V, but I didn't know if it's a recommendation or a requirement.

Do you mean the readings will be incorrect at all, or do I just need to calibrate the probe?
From what I see, all parts of the circuit can operate at 3 V

Welcome!
Although 3.3V would get it working, but the readings are not correct actually, as you could read on the wiki that Please use an external stable power supply(such as 7.5V DC),and the voltage of MCU system as close as possible to the +5.00V. More accurate the voltage, more higher the accuracy!
Other water sensors are also 5V compatible instead of 3.3V.
