Had no problems with software or getting hardware to work with GPIO on RPi3B+. Will have to solder connections to sensor though.
We have not received the item, pleas give the freight code etc that I can seek it, I badly need that, the product development of the proto is staying now
I followed the Python example code, but translated it into Ruby. The S8 tended to start timing out on reads after running for a few hours. I upped the timeout parameter to 1 second from a half second and still had timeouts. Also made sure to sleep for a half sec after sending read request, and slept for a couple of seconds between read requests. Flushing input as well.
I am running it USB from a Raspberry Pi Zero. I have had no problems with this same configuration with the Cozir sensor.
Also, the Python example in the application note sends a command of 0x44, whereas the Senseair Modbus document shows 0x04 as the read register command. I tried that and it timed out every time, whereas with 0x44 at least it read for a couple of hours.
Puzzling. I could not recommend this unit as it stands.
