Hi there,
just trying out the turbidity sensor and had a couple of questions:

- is there a link for the schematic of the gravity board somewhere?- Is it better to operate the sensor in a dark environment or is there any build-in filter in the receiver? - can it be powered with 3,3V or is that prone to measurements errors ?

Thanks for the help

1.The link for the schematic of the SEN0189 Gravity: Analog Turbidity Sensor for Arduino board is here:

https://github.com/Arduinolibrary/DFRobot_Turbidity_sensor/blob/master/SEN0189%20Turbidity%20sensor(V1.0)%20schematic.pdf

2.You do not have to, you can adjust the threshold potentiometer on it to do calibration.

3.No, it can only powered by 5V.
