Status:
EZO Carrier Click - ORP is a compact add-on board suitable for determining a liquid's oxidation/reduction potential in your application. This board features the EZO-ORP™, an ISO 11271 compliant embedded ORP circuit board from Atlas Scientific. The EZO-ORP™ is a small blue additional board that comes with the carrier board and allows you to measure electron activity in a liquid in a range of -1019.9mV up to +1019.9mV with an accuracy of +/-1mV. The EZO-ORP™ allows readings in a maximum of one reading per second. This Click board™ is ideal for providing information on the liquid quality and degree of pollution, if present, from water sterilization to chemical production. It is compatible with various measurement probes, such as the Consumer Grade ORP Probe from Atlas Scientific.
EZO Carrier Click - ORP 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 - ORP is based on the EZO-ORP™, an ISO 11271 compliant embedded ORP (Oxidation/Reduction Potential) circuit board from Atlas Scientific. It allows you to interface any type and brand of measurement probe, which determines the liquid's oxidation/reduction potential in your application, by sinking the probe into the solvent you want to measure the electron activity. The EZO Carrier Click - ORP comes with the SMA connector for interfacing the appropriate probe, like the Consumer Grade ORP probe.
The EZO-ORP™ 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. This circuit is a very sensitive device, and the sensitivity is what gives this circuit its accuracy. It can read micro-voltages that are bleeding into the water from unnatural sources such as pumps, solenoid valves, or other probes/sensors. 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 - ORP 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-ORP™ 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.
