How to retrieve data from RS485 sensor with AB02s board

#1

Recently I just start to use AB02s board to get data from a sensor, that is RS485 protocol. So my project is very similar to this tutorial but after following this tutorial, I stuck with this error “fatal error: SoftwareSerial.h: No such file or directory”. At this point can someone point me?
Would it work with AB02S or not if I follow this tutorial? if it’s work, where should I download this library?
