The CN0428_example is a demo using the EVAL-CN0428-EBZ, the EVAL-M355-ARDZ-INT and the Arduino Uno board as a system to detect several important parameters that affect water quality, including chemical indicators, biological and bacteriological indicators and even some low level contaminants like heavy metals.
The CN0428 circuit shown is a modular sensing platform that allows the user to design a flexible electrochemical water quality measurement solution. Its high level of integration enables an electrochemical measurement platform applicable to a variety of water quality probes including pH, oxidation reduction potential (ORP), and conductivity cells.
Using the specified setup the system is capable of measuring pH, Conductivity, Temperature and ORP of a solution. It can be configured for customized measurements such as Dissolved Oxygen (DO) measurement, Ion Concentration measurement, i.e., Ion Selective Electrode (ISE) measurement and many other water quality factors. Up to 4 sensor boards can be connected for measurements simultaneousl and temperature can be measured on one or all sensor boards.
The following is a list of items needed in order to replicate this demo.
We recommend not opening the project directly, but rather make a local copy in your workspace and open it using Arduino/Genuino IDE.
The source code and include files of the CN0428_example can be found here:
The CN0411_example is a C Arduino sketch. All files are in the same folder as the .ino file and include the source and header files.
These two steps can also be done using the quick buttons on the Arduino sketch. Check out the image below for locations of the quick buttons.
Data is output using the USB cable from the Arduino to the PC. The USB port acts as a serial terminal to display the data being transmitted via UART. Opening the serial terminal window from the Arduino IDE is very easy, simply click on the button shown in the picture below.
You may need to configure the serial terminal depending on the current settings of the Arduino IDE. Make sure the settings are as follows:
Select COM Port Baud rate: 115200 Data: 8 bit Parity: none Stop: 1 bit Flow Control: none
The Arduino tools are easy to use, and there are many tutorials and users guides to help learn how to use the Arduino IDE.
