i am new here and i don’s have much knowledge in the area of programming (arduino’s or anything else) but hopefully that will change
i have come across a Thies Clima ultrasonic wind sensor, and i would very much like to get that turned into part of a weather station. it uses RS485 MODBUS or thies interpretation to display wind speed, direction and temperature.
if i use the Thies software i can get the data in a serial monitor, by using an RS485 to USB converter. so i know i have the wirering ad the connection data correct.
the problem with that is that it is too limited, and i would like to get the data by using an Arduino so that in the long run i can add more sensors (pressure or rainfall) and possibly add it to a web server using a raspberry pi.
but my main problem is that i cannot seem to get any sketch that works, and every application of this RS485 seems to be a completely different code.
so i was hoping that one or more of you could help me out with the basics for a sketch. basically just setting the Arduino to master, reading the data and then displaying it in the serial monitor.
i have added a picture of the MODBUS settings for the unit and the manual for it.
i know how to work with the hardware, i just dont know how to make the code, once i have a code i can usualy see how it works. i just dont have the experience to write it from scratch
the unit is programmed up to start sending data as soon as it boots up, in MODBUS mode it sends a long string of HEX code, and in Thies mode it just sends 3 numbers on 1 line (speed, direction and temp)
i hope one of you can help me out with the basic code for getting data.
