특징
- EZO Carrier Click - Oxygen is a compact add-on board suitable for determining the dissolved oxygen of a liquid in your application. This board features the EZO-DO™, an ISO 5814 compliant embedded dissolved oxygen circuit board from Atlas Scientific. The EZO-DO™ is a small yellow additional board that comes with the carrier board and allows you to read the oxygen values in a range of 0.01 up to 100 mg/L with an accuracy of +/-0.05mg/L. The EZO-DO™ allows readings in a maximum of one reading per second. This Click board™ is ideal for electrochemical sensing and also capable of reading micro-voltages that are bleeding into the water from unnatural sources such as pumps, solenoid valves, or other probes/sensors. It is compatible with various galvanic measurement probes, such as the Conductivity Probe K 1.0 from Atlas Scientific.

HOW DOES IT WORK?
EZO Carrier Click - Oxygen is based on the EZO-DO™, an ISO 5814 compliant embedded dissolved oxygen circuit board from Atlas Scientific. It allows you to interface any galvanic measurement probe, which determines the dissolved oxygen of a liquid in your application, by sinking the probe into the solvent you want to measure the oxygen. The EZO Carrier Click - Oxygen comes with the BNC connector for interfacing the appropriate probe, which MIKROE also offers. The EZO-DO™ 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.
The EZO-DO™ 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. The EZO-DO™ has a flexible calibration protocol allowing for single-point, two-point, or three-point calibration. The temperature compensation should be taken into account. The EZO-DO™ 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.
EZO Carrier Click - Oxygen 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.
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.
