Remember that we are running N3uron on the Seeed Studio EdgeBox RPI200. And now it’s time to access to the N3uron application to access to the Modbus data generated by the Seeed Studio Temperature and Humidity sensor.
To access to N3uron, copy your local ip address and paste it on a browser using the port 8003 (e.g. http://192.168.1.53:8003/).
Use the credentials admin and n3uron to access to the N3uron platform.
Click Config on the left menu and go to Modules on the Explorer menu and click New Module.
I called the module Modbus and selected the ModbusClient type.
Now go to the Explorer menu, click Modbus and click to create a New Channel. I called it ModbusChannel.
As we are connecting a Modbus Serial device, I selected Serial type and then the port name as /dev/ttyACM0 as this sensor is using the RS485. Create a device there, I called it SHT-1 and I left the default parameters as they matched with the parameters from the sensor manual.
Now, we need to create Tags. Go to the Explorer menu on Tags. Create the first tag (e.g. Temperature) and add all the parameters needed. The temperature register from the device is on the address 40001.
Afterthat, duplicte the Tag and just change the address to read from the right address, in this case the 40002.
Go to Real Time on the left menu, and you should be able to see the data streaming into the n3uron application.
Next experiments with the Seeed Studio EdgeBox RPI200 will include more data such as the Modbus TCP, send data over MQTT and more.
Stay tunned!
