Thanks for your help, Shannon! I appreciate it.

The EnviroDIY Mayfly Data Logger board is unlike standard Arduino boards (like the Uno) in so many ways that there was no easy way to use the regular Arduino board pinouts on the Mayfly.  So that means accessory boards that are meant to plug into a standard Arduino board will not work.  I’m not familiar with the isolator boards used with Atlas S…[Read more]

Hi there! I’m hoping to do something similar to what David is doing. I’m using a couple Xbee Pro 900HP modules and couple Mayfly’s. I’m setting up the network using PlatformIO and I came across a roadblock with some of my code. The code runs, printing data to the Mayfly’s SD card until I add the the Xbee code to the loop(). Once I added the Xbee…[Read more]

@james-dareboprc-govt-nz, those power issues you came across on GitHub (regarding getting the brush to spin and wondering about setting the spin rate) were quite old (2017?) when we first started using YosemiTech sensors and early in my knowledge of DIY electronics. The short-story is that once we figured out that we needed to add a capacitor…[Read more]

Thanks Anthony! I’m feeling a lot more comfortable about Yosemitech sensors now that I have a test unit in my hands. I can’t wait to get them out in the field.

Also, for anyone who is interested.  My solution to testing multiple TTL-RS485 adapters with one rig can be seen in the attached photo.

Hi @aufdenkampe,

That’s really good news.  Yes I was reading through some historical issues on git-hub about problems with the Polou step-up module and inability to set brush intervals. My 511-A seems to be functioning well so I’m assuming the Polou step-up issue is also solved.

One quick question, In your view, is the 511-A worth the extra…[Read more]

James, I’m glad to see that you’re using our DIY Mayfly-Modbus-Wing. Yes, soldering the DIY windshield is required. I had thought you were discussing soldering an RS485 adapter directly to the Mayfly. My bad for misunderstanding!

From my perspective, there is not “problem” with the YosemiTech Y511 turbidity brush running every time the sensor…[Read more]

Hi @shicks. Thank you. I was considering pogo pins. I assume you just solder them in and push the adapter board down to test? I guess I could also solder female headers into the wingshield holes and males into the adapter boards. This would allow me to test each adapter board on one rig, and I could just solder the male headers into new wing…[Read more]

James, I really like all the YosemiTech sensors I’ve used, and I’ve facilitated the purchase of approximately ~150 or more for various organizations. The Y511 turbidity sensor with wiper is the most common we use, and everyone is very satisfied with it.

I’ve been working with a water utility, and after doing a careful comparison with their other…[Read more]

James, by the way, I would suggest that you NOT solder anything to the wing headers. Our two options just plug into them and can be removed anytime, just like an Arduino shield.

James, we’ve been playing with hardware designed for this for quite some time (as a subfolder in our SensorModbusMaster repo), and just recently spun our commits/designs into it’s own Mayfly-Modbus-Wing repo. Have you seen this?

Our solder-your own DIY version is described here: https://github.com/EnviroDIY/Mayfly-Modbus-Wing/tree/master/Modbus-Ma…[Read more]

It depends on what kind of pinout is on the adapter board.  I’m not familiar with them since I don’t use them, but you could probably make a test jig with pogo pins, or if the board have plated-through holes you can simply use male header pins and just hold the board at a bit of an angle to  make contact.
