    I have a problem in communication between arduino uno and yosemitech Y504-A (http://yosemitech.sell.everychina.com/p-101690172-y502-a-online-optical-dissolved-oxygen-sensor.html). I use MAX485 module (https://hobbycomponents.com/wired-wireless/663-max485-rs485-transceiver-module). Honestly I am new in Modbus, so please teach me how to solve or connect with sensor to read data. Thank you.
