I forgot to mention that YosemiTech also makes a multi-parameter sonde with an optional wiper. https://www.yosemitech.com/en/product-20.html
This is an approach to having a wiper on the DO probe, as none of the stand-alone DO probes have a wiper (unlike Turbidity, Chlorophyl and Blue-Green Algal stand-alone sensors, which have models with built-in…[Read more]

I highly recommend the YosemiTech DO sensors, which use optical sensing technology for long-term stability. https://www.yosemitech.com/en/product-cat-11.html
They use Modbus communication and can be user-calibrated. Here are their two main models (the Y505 is new and not on their website).
Y504 (standard model):
~$650 each (plus shipping plus…

Based on the list of supported sensors (https://github.com/EnviroDIY/ModularSensors), it looks like a Yosemitech DO sensor is another option.

You might want to check out Atlas Scientific DO sensors (https://www.atlas-scientific.com/product_pages/kits/do_kit.html). They are galvanic probes that are cheap and fairly accurate (+- 0.05 mg/l), but they do require a fair bit of effort to piece together. You would need the DO kit (previous link, $280), an isolated carrier board ($40, https://w…[Read more]

I’m working with a watershed groups located in a watershed with intense CAFO activity. They are interested in monitoring DO continuously using the Mayfly EnviroDIY Monitoring Station. I was recommended the Zebra-Tech Optical DO sensor which costs nearly 3500. I’m sure this is a great sensor but is a little expensive for this group. Any…[Read more]

Hi:
I’m loading the sketch driver to MB7383 sensor
The driver sketch is from here: https://www.envirodiy.org/mayfly/software/ultrasonic-sensor/
However, I got an error showing in the attached image, anyone know how to solve it? Thanks!
