Hi, all. I probably made a mistake jumping into an Edge Control too soon, but nonetheless here I am, wondering what "watermark sensor" means. Is it to connect a pressure sensor to tell how deep is the water level of a deposit or something alike? https://www.amazon.es/Sensor-presión-precisión-señal…

OK, I see it now: [image] But that page is just the glossy marketing overview - dig into the full documentation for details: [image] [image]

If you use your favourite search engine and look up "Watermark Sensor" you will find that it is a particular type of soil moisture sensor. Irrometer Watermark Sensor

"WATERMARK" seems to be a proprietary, patented technology from Irrometer: [image] 200SS . The suggested circuit there: [image] does seem to correspond to the diagram in the Edge Control Data Sheet: [image]

If you look at the Arduino Edge Control PCB Schematic , you will see the 16 inputs on page 5 out of 8: [Watermark Inputs] and some additional circuitry on page 3 out of 8: [From Watermark Sensor]

What would you look for at the soil moisture sensors from arduino store to find out if they are compatible? The search was inconclusive for me, and tried to avoid the "Soil" keyword in the search since I could only see it that one occurrence on the documentation that you referred to. Although now t…

[image] josiin: What would you look for at the soil moisture sensors from arduino store to find out if they are compatible? I agree that the documentation on this is poor. As these inputs have clearly been designed for a specific 3rd-party proprietary part, they should have named the manufac…

Found this on their FAQ page: [image] So (they say) not just "a simple plain analog voltage input" ? The "Integration Guide" is here: https://www.irrometer.com/200ss.html - but no mention of the Arduino Edge Control.

Weird Arduino manufactures soil moisture sensors and not tell how to use them, right? May be they are third party. That paragraph regarding the voltage output adapter is kind of hinting why there were issues for the guy at the thread about the precision issues with this reading. Perhaps he was miss…

What sensors are the Watermark sensor pins meant for?

I don't think they manufacture them - they're just listing a 3rd-party product in their store?

I agree, it's bad that they don't make this clear.

EDIT

It seems to be common practice.

eg, this is clearly a 3rd-Party product (from DFrobot; it has their name on it!), but there's no mention of that in the text:

and "Gravity" is a DFrobot brand:
