oh that sounds cool as hell... yeah man, show me!!!



so the digital would either be an off or on option, like all or nothing. where as analog could give a variable output from say 1 to 10 and anywhere in between.

the "megas" can read up to 16 analog inputs. that just happens to be the same number of plants i grow!!!!

Ok glad I'm not the only that has not heard about leaf sensors...haha...I just learned this last night....regardless how ever accurate it may be...

Leaf Sensors for Precision Agriculture

Leaf sensors can tell farmers when crops need to be watered | Penn State University

Plant-based sensors that measure the thickness and electrical capacitance of leaves show great promise for telling farmers when to activate their irrigation systems, preventing both water waste and parched plants, according to researchers in Penn State's College of Agricultural Sciences.

looks like plastic and some wire and a pcb board? Copper wires? I don't know that stuff as well/terminology

But here's some of the info

Figure you and moe know or could figure out more about this and coding the software, And 3d printing the hardware.

And wanted yalls opinion, maybe this could be another cheap tool/sensor easily manufactured.

so these sensors actually measure the thickness of the leaf to determine moisture... brilliant!!!!!!!!!!

Yup

I find it little crazy I've not seen this on any grow forum lol

wow $130 per sensor.. 16 sensors = $2080 for my setup.. the rest is all doable and can be DIY.

.

yeah i googled your "leaf sensor" and it one of the first results!!! haha

Yea that price is insane I figured you could make this so much cheaper and then tell me how lol =)

maybe buy just one and backward engineer it...

it might just be a measuring laser that shines through the leaf.

it might need to be calibrated for each individual plant.. measure the leaf when the plant is happy, then measure when dry. then tell the computer to look for those numbers from the sensor and react however you tell it.

not hard to connect or program really. just depends on the accuracy of the measurement.

these here measure the moisture on the leaf itself, for the price it might just be worth a try!!

i did see a calibration page somewhere, i think on the first link, the aeroponics page link

That doesn't sound too difficult to calibrate per batch either, one could dry out the plant and take measurements with the right device in a consistently controlled environment.

Unfortunately it doesn’t sound like you could use one and run multiple leads to plants. Unless the board has multiple contact points. Out of my zone of knowledge.

I can already check just one plant pretty easy. I would want it to check each plant individually. I was reading more and those sensors measure the rhickness and the electrical capacitance at the same time. That cheap one on zon only saw the capacitance of the leaf. I already know that's not enough. You see this in your space I'm sure where a leaf rests on something it's always wet under it. If that sensor sits there it's only accurate to an extent.

Yes, usually another leaf.
