Guide for RS485 Wind Speed Sensor on Arduino
ZickZack 2022-06-21 09:01:16 1970 Views5 Replies I am trying to figure out how to connect the Wind Sensor (DFR0845) using the RS485 to RS232 (SEN0483) to an Arduino (Z-Uno).
Is there any guide I am Missing? I only find guides for Raspberry Pi but I need the sketch for Arduino.
I guess this is one part of the puzzle:

Thanks
i looked at the tutorials and am trying to get it to work on a mega with no luck.
I can get the wind direction meter working perfectly with the library, but when i try the speed sensor code, it fails to compile with a lot of errors.
I am using serial1 on the mega for the sensors.
do they have an arduino library for the speed sensor, as it looks like only a raspberry pi library
Adamants Here are tutorials

DAI.DAI Hi, I'm a noob wanting to connect an RS485 Wind Speed Sensor (SEN0483) to an Arduino Metro. I saw a post in which someone asked for the code to make this work (thx!) but I'd really need a wiring diagram to make certain I have the right hardware and that I've connected everything together properly.
The Arduino doesn't have enough power to drive the SEN0483 for example, and I'm not sure how to properly hook up a second power supply without frying the Arduino in the process. I think the DFR0845 module is how to connect the SEN0483 to Arduino but again, a wiring diagram sure would give me the confidence to give it a go.
Can anyone assist on this?
Thx, Dan
Daniel.LIGHT This project uses a wind speed sensor connected to an Arduino board to measure wind speed. This can then be used to determine how much power your fan needs to run at different speeds.
