Status:
EZO Carrier Click - Conductivity is a compact add-on board for measuring conductivity, salinity, and Total Dissolved Solids (TDS) in various applications from chemical production to hydroponics. This board features the EZO-EC™, an ISO 7888 compliant embedded conductivity circuit board from Atlas Scientific. The EZO-EC™ is a small green additional board that comes together with the carrier board and allows you to read a conductivity in a range of 0.07 to over 500,000μS/cm. Still, it can also accurately measure salinity up to 42 PSU (ppt), TDS as ppm, and the specific gravity of seawater between 1.00 and 1.300. This Click board™ is ideal for reliable water chemistry measurements, supporting probes ranging from K 0.01 to K 10.2 of any brand, such as the Conductivity Probe K 1.0 from Atlas Scientific.
EZO Carrier Click is fully compatible with the mikroBUS™ socket and can be used on any host system supporting the mikroBUS™ standard. It comes with the mikroSDK open-source libraries, offering unparalleled flexibility for evaluation and customization. What sets this Click board™ apart is the groundbreaking ClickID feature, enabling your host system to seamlessly and automatically detect and identify this add-on board.

EZO Carrier Click - Conductivity is based on the EZO-EC™, an ISO 7888 compliant embedded conductivity circuit board from Atlas Scientific. This is a versatile and accurate solution for measuring conductivity, salinity, and Total Dissolved Solids (TDS) in various applications from chemical production to hydroponics. With a conductivity range of 0.07 to over 500,000 μS/cm, it can also accurately measure salinity up to 42 PSU (ppt), TDS as ppm, and specific gravity of seawater between 1.00 and 1.300. This advanced module offers the precision and functionality comparable to high-end bench-top conductivity meters, making it an ideal choice for embedding into projects that require reliable water chemistry measurements.
Boasting an accuracy of +/- 2% and a quick EC reading time of 600ms, the EZO-EC™ supports probes ranging from K 0.01 to K 10.2 of any brand. It allows for both two-point and three-point calibration, ensuring precise measurements. Additionally, it features temperature compensation for more accurate readings across various conditions.
This circuit is a very sensitive device, and the sensitivity gives it its accuracy. That’s why the EZO-EC™ needs to be isolated from the host MCU; therefore, this Click™ board comes with the Si8400AB, a bidirectional isolator from Skyworks. The isolator provides standard bidirectional and I2C communication with a clock frequency of up to 1.7MHz. So, to eliminate the electrical noise, besides the Si8400AB isolator, the power supply voltage is also isolated. For this purpose, this Click™ board is equipped with the ROE-0505S, a DC/DC converter from Recom.
EZO Carrier Click - Conductivity can use a standard 2-wire UART interface to communicate with the host MCU with the default baud rate of 9600bps. While using the UART interface, you can use the library we provide or a simple ASCII set of commands. You can also choose a standard 2-wire I2C interface over the COMM SEL jumpers. From calibration to timed readings, the Atlas Scientific EZO-EC™ circuit is a drop-in solution to a complex measurement. It features sleep mode, continuous operation, find function, export/import calibration, on-module status LED, and many more features detailed and described in the attached datasheet.
This Click board™ can operate with either 3.3V or 5V logic voltage levels selected via the VCC SEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MIKROE compilers.
This Click board™ is supported with mikroSDK - MIKROE Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
For more information about mikroSDK, visit the official page.
NOTE: Please be advised that any peripheral devices or accessories shown connected to the Click board™ are not included in the package. Check their availability in our shop or in the YMAN section below.
