Good day! I just want to ask what will be the connection when I have used 2 sensors particularly soil ph sensor and npk sensor in arduino through rs485?
How many rs485 will I use if I want to connect the 2 sensors in just 1 arduino?
Thank you so much!
Moved to the Project Guidance section.
You need 2 RS485 receivers connected to the Arduino unless You find a 2 channel receiver.
What should be the connection? Thank you so much!
Any pins that can be used for software serial.
