@aufdenkampe do you have any feedback about YOSEMITECH turbidity sensors? My questions are:

1) Are they as reliable as other turbidity sensors, i.e. do they drift more readily, or provide strange values? For $510USD (non-wiper) or $680USD (wiper), they seem like a good deal.

2) Is it worth getting the wiper version over the non-wiper version?

3) We have a YSI multi-sonde deployed for another project using a modbus wing. Our technicians noted that the wiper powers on every-time the Mayfly connects to the probe, draining the battery. Is this the same for the YOSEMITECH sensors or is there a way around this?

3) How much does the RS485-to-TTL interface board cost to build?

Thanks for your help.
