Hi,
I want to read data to Arduino Uno from an ultrasound liquid level sensor DS1603DA.
Similar post I found was this: How to read serial data from Non-contact Ultrasonic liquid level sensor - Sensors - Arduino Forum
However here is an RS-485 communication.
Question - how should I wire it? And do I need some additional components?
Has anyone worked with this sensor?
You need a MAX485, such as this: RS485-Modules - ArduinoInfo There's plenty of information on the internet about how to connect the MAX485 to an Arduino.
Thank you, this make sense.
I also found a potential wiring diagram in another post: Reading Sensor values digitally with RS485 - Science and Measurement - Arduino Forum
Could this circuit be good for my Uno?
And is it OK if my sensor requires (as I understand) 10-36 V supply?
I mean, it will now be through this MAX485, but is it still safe for Arduino side?
