Awesome question. They have two sets of sensors. One is for pressure. The other is a default resistance that runs in parallel along the length of the device. That resistance is used for temperature compensation. When you bridge the two together, temperature effects them equally and by...

Here is an example of what was achieved. What is shown in the above figure is a continuous water level measurement of the water level in my sump displayed in inches. The signal was brought into the Hydros using one of the 0-10V input lines of my X4. I calibrated the system to the water level...

After posting some of this on Facebook, I was asked to start a thread here about my experiences with the Milone Technology Continuous water level sensors. I will be adding to the thread here, but here is a little introduction. Many types of water level detectors exist. Most however, have been...

Interesting. Most relays are electrically activated mechanical devices. Because of that... they tend to bounce more, they are audible when they open and close (sometimes I like that), they can stick as well, they typically require more power to activate and they take a little longer to...

That Oono module is nice. It is very similar. One with relays one with FETs. It is nice that it is enclosed. I'm just looking to make something that is more plug and play. I know some don't like the GX12 connectors. I happen to like them. I also wanted a system where anything that...

Yeah. A friend of mine pointed them out when I mentioned the application. It is crazy flexible. I thought of buying two of them --- one that I could hook up to 12V and another that I could hook up 24V. Most devices are either 12 or 24. These can also carry more power than the drive outputs...

I have one of these coming in on Wed that I'm going to try out. https://www.amazon.com/gp/product/B07PS2C4YP/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 These are pretty cheap. They are also flexible. They will control 5A if you have the power supply that can deliver it. I'm going to...

Hmm. I don't have the 1" Gredia. I have the 1.5 and its diameter is what you might expect. The 0.5 inch looked pretty good to me as well. It is hard to determine the overall impact if you don't have one to compare against another... so it was good you have both. The wiring thing threw me...

A bit surprising, but for all the bad press that the Neptune ones received -- I didn't think they were all that bad. They all restrict flow to some extent. The blades of the turbine are oriented differently than the Gredia. I figured I had nothing to lose with the Neptune sensor. No one...

I've done both at this point. I reverse engineered my 1" Neptune sensor and its working fine. I've also added on two other 0.5" Gredia flow sensors to my reactors. They are working great. Mine have all been working very consistently.

I think I bought the adaptor for it on amazon. I'll have to look. I've been frustrated with readapting neptune stuff lately. I'm close to having the level sensors work, but they are wired a touch differently in their FMM in comparison to the cheap, nearly identical, Chinese level sensors...

You are correct. I drafted the email from work without looking at the connector.

You will need to solder a GX12 connector on to it (3pin). Just make sure you wire it with the output going into the digital input of the sensor inputs.

I tried the one from amazon and I was able to interface it successfully and get a rate. I'm not sure if the rate is calibrated properly (and will wait for the software upgrade on this). My one concern is that the largest flow sensor (1.5") has a tiny amount of metal within a ring on the inside...

Fun stuff.... This is my version of controlling outlets. I built an interface from the 0-10V outputs to control a standard piece of equipment. The movie shows me turning on and off a halogen lamp with the 0-10V outputs of the Hydros. I built two channels on this device in the event that I...

Actually, this has been a good exercise. I took a closer look at their circuit and missed that their ladder didn't have a resistor on the first switch.... So a 2k resistor between pins 1 and 3 should give 0, 1.24, 2.44, 3.3, and around 5V. I think it is worth a $6 gamble for the group.

It should work with a 8k resistor between pins 1 and 3. That should give you voltages of 0.85, 1.86, 2.75, 3.83, and 5V.

It is pretty close if you put a 1k resistor across pins 1 and 3 to lower the input impedance.

I guess I wasn't clear. External --- meaning a plug in +5V supply vs taking it off of one of the connectors like the input connector or the sensor connector. That said, I now realize that the sensor channels can't be set up as triggers like the inputs can. My calculation is that the max...

Its worth a $6 gamble. It is just a matter of setting up the triggers for specific voltages on the software side. I like challenges. Would you like to wager?
