Atlas-Scientific EZO Devices Simple Read over i2c Example
This is an extremely basic Flow for reading data, via the i2c inteface, from most of the Atlas-Scientific EZO sensors, circuits and devices:
RTD, pH, ORP, EC, DO, FLO, PMP, HUM
The folowing are not included, but the above code will be very easy to modify to accomodate them:
PRS, O2, CO2
Recall the intent of this flow is to help users to retrieve very basic measurements from the EZO devices and work with those values in Node-RED. Therefore, there are no provisions for configuration, calibration, compensation (e.g. temp comp for pH), nor database logging in this example.
This example assumes the default i2c addresses are in use. The devices must be configured to output the variables that are retrieved by the example. A few node-RED nodes must be installed. There are comments throughout the flow that indicate which variables are being retrieved.
I hope some will find this very basic flow useful. I will continue to publish much more complex examples of flows that include some configuration, calibration, compensantion and data logging capabilities.
