Frequently Asked Questions

What is the operating voltage range for this Grove EC Sensor?

The sensor driver board is designed to operate on either 3.3V or 5V DC power supplied via the Grove connector. This dual-voltage compatibility allows it to work directly with most Arduino boards (5V), Raspberry Pi (3.3V), and other common microcontroller platforms without requiring an external level shifter.

How do I connect the EC probe and read data with an Arduino?

Connect the driver board to your Arduino's 5V, GND, and an analog input pin using the included Grove cable (or standard Jumper wires). The EC probe attaches via the BNC connector on the board. The board outputs an analog voltage proportional to conductivity. You will need to implement a calibration routine using known conductivity solutions to convert the raw ADC reading into accurate µS/cm values.

What does the measurement range of 0-2000 µS/cm cover?

This range is suitable for monitoring freshwater, nutrient solutions in hydroponics, and aquaculture. It covers typical drinking water (50-500 µS/cm), hydroponic nutrient mixes (800-2000 µS/cm), and can indicate general water quality degradation. For measuring highly conductive solutions like seawater, a sensor with a higher range would be required.

Is the EC probe suitable for continuous submersion?

Yes, the probe is constructed for use in aqueous environments and can be continuously submerged for monitoring applications. For long-term deployment, periodic cleaning is recommended to prevent biofilm or mineral scaling on the electrodes, which can affect measurement accuracy over time.
