Overview
DFRobot Gravity: analog electrical conductivity meter V2 is specially used to measure the electrical conductivity of an aqueous solution, and then to evaluate the water quality, which is often used in water culture, aquaculture, environmental water detection, and other fields. You may also check Liquid Sensor Selection Guide to get better familiar with our liquid sensor series.
This ec meter product, as an upgraded version of the electrical conductivity meter V1, greatly improves the user experience and data precision. It supports 3~5v wide voltage input, and is compatible with 5V and 3.3V main control board; The output signal filtered by hardware has low jitters; The excitation source adopts AC signal, which effectively reduces the polarization effect, improves the precision, and prolongs the life of the probe; The software library uses two-point calibration method, and can automatically identify standard buffer solution, so simple and convenient.
With this product, the main control board (such as Arduino), and the software library, you can quickly build an electrical conductivity meter, plug, and play, no welding. DFRobot provides a variety of water quality sensor products, uniform size, and interface, not only meet the needs of various water quality testing but also suitable for the DIY of multi-parameter water quality tester.
Conductivity is the reciprocal of the resistance, which is related to the ability of the material to carry the current. In the liquid, the reciprocal of the resistance, the conductivity, is the measure of its ability to conduct electricity. Conductivity is an important parameter of water quality. It can reflect the extent of electrolytes present in water.
Tips:
In order to ensure measurement accuracy, it is strongly recommended to add a temperature sensor to measure the temperature and achieve automatic temperature compensation.

Easy data logging with grove sensors using the MKR Connector Carrier and MKR boards
Say hello to the newest member of the Arduino family! The MKRZero--now available on our stores at the price of $21.90/€20.90 (+ tax)--shrinks the functionality of the Arduino Zero down into an Arduino MKR1000 form factor, making it a great educational tool for learning about 32-bit application development. Like the Zero, the latest board is based on a Microchip SAM D21 ARM Cortex®-M0+ MCU. An integrated SD connector with dedicated SPI interfaces (SPI1) allows you to play with files without any extra hardware, while an analog converter enables you to monitor its battery voltage. The MKRZero’s features in a nutshell: small form factor number crunching capability low power consumption integrated battery management USB host integrated SD management programmable SPI, I2C and UART Interested? You can explore the MKRZero in more detail, including its technical documentation, via the links below: Product Page Getting Started Guide Tutorials on Project Hub Make a ScheduledDataLogging Create a I2S synth generator (theremin) Read battery voltage Make it rain On the software side: If you use the Arduino IDE, you will need to add the new Intel SAMD Core, selecting Tools menu, then Boards, and last Boards Manager on the Arduino Software (IDE). If you use Arduino Web Editor, everything is already updated! Watch out music makers, we’ve got some news for you! We have released two libraries for your enjoyment: Arduino Sound library - a simple way to play and analyze audio data using Arduino on SAM D21-based boards. I2S library - to use the I2S protocol on SAMD21-based boards. For those who don’t know, I2S (Inter-IC Sound) is an electrical serial bus interface standard for connecting digital audio devices.
