The EVAL-CN0409-ARDZ shield is a low to high level water turbidity measurement system in combination with the EVAL-ADICUP360. It uses the ADPD105's ambient light rejection feature to make it ideal for applications where accurate, robust and non-contact turbidity measurements are critical.
When the project is being run for the first time a calibration procedure is required in order to achieve high accuracy results. The user must follow the steps described in the UART terminal when the application is started.
The user has the option to modify the solutions that are used for calibrating the device. Any values can be used for the points that are used for calibration, but a proper distribution along the 0 - 1000 NTU range must be taken into account. This values can be edited in CN0409.h file inside the include folder within the project structure.
The following is a list of items needed in order to replicate this demo.
To obtain a most accurate results when taking measurements, process below should take into considerations:
We recommend not opening the project directly, but rather import it into CCES and make a local copy in your workspace.
