I was asked to build a complicated (for my beginner level) sensor network across a large area (a few hundred meters). The area can be broken down into four major groups based on location. Within these groups, the sensors are still located up to a few hundred feet apart.
Because the sensor wires will be long, i would like to use 4 to 20mA sensors. I will connect these sensors back to the Arduino using a special connector -
There will be up to eight (8) 4 to 20mA sensors (measuring water tank levels) on each arduino.
The Arduinos will all need to talk to a master ardunio that i will keep connected to a computer and make a graphical user interface using other software with input from the sensor data.
Can i use RS485 with Mudubus for the link between the Arduinos? Will the RS485 interfere with the use of the i2c on the arduino?
Since they are tank level sensors, i want to continuously monitor the sensors (lets say at a minimum of every 10 seconds).
