I just say an article about IBM usibg salt as a battery. Maybe it is based on this experiment.

I noticed you used a peristaltic pump. any reason for that choice? I usually only consider them for accurate dosing when used with a stepper motor. That 's a regular brushed motor.....

I usually choose what I have on hand or what I can get cheap. I've used a few Marine wash down and bilge pumps.

I even got a couple of these diaphragm pumps: G21177A - (Pkg 2) Low Price 12VDC Flojet Pump

they need special fittings but that's easy to make...

Looks like a nice project. I bought the exact same sensor. sorry to hear it failed. I think I'll solder some 1/4in copper tubing to mine and place it in a weatherproof box with just the new legs sticking out..

I have a couple of 55 gal drums on my gutter downspout. I wanted to do something similar but never had the time. I even tried to convince a friend to try it with a jug from the water cooler. I use a regular wash-down pump to supply a standard garden hose sprinkler. It still a manual thing.

we talked about so many options like a i2c light or UV seniors to make sure it doesn't start up in bright sunlight.

then we said rain sensor to make sure if it starts raining it will shut off water.

now i think a sensor monitor that checks that the sensor readings vary every day is another feature..

I may never build mine but its nice to see your progress...

Bad news: The soil hygrometer which i used in this project has stopped working. It still gives a signal which no longer changes (has been at 183 for the past 4 days), but it turns out that the metal layer on the prongs which is buried in the soil has corroded away. Good thing that i noticed the strange behavior and investigated further before my olive tree died! Very sad. I was aware of the danger of using this cheap sensor at an early stage, but - unfortunately - i cannot afford a better solution. Am very curious about the Vegetronix VH400, but it is expensive - especially after the shipping charges and customs fees to Norway. Anyway - i guess that puts an end of this project. I hoped to make a pcb board and enclosure eventually. The sketch should also be modified to log the watering intervals and the amount of water that was used - possibly with other relevant data (at least temperature and humidity).

edit: A friend pointed out that I needed a video to properly finish up the blog post [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-5667be73-9f47-4cff-ac01-0c5f649772b6/3113.contentimage_5F00_1.png:16:16]

So I video'd a little bit of data logging, some impatience, some re-programming of the ESP-01 with my adapter board, some more data logging.

And I cut out all of the embarrassing failures and awkward pauses. You're welcome [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-5667be73-9f47-4cff-ac01-0c5f649772b6/3617.contentimage_5F00_3.png:16:16]

Great project for a more unusual use. Well done.

Kind regards

Great Project.

Why haven't you added the trailer lights software ...you know you'll end up using it [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-5667be73-9f47-4cff-ac01-0c5f649772b6/contentimage_5F00_938.png:16:16]

Very nice project and write-up. We have used small light bulbs to help protect tender plants from frost and/or freezing during winter. It is a simple method to apply a few degrees to an isolated area. Well done! And thanks for taking care of the little hummers!

Nice project, Nico. Very useful for anyone wanting to program an ESP-01, and collect data - I may need that [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-5667be73-9f47-4cff-ac01-0c5f649772b6/contentimage_5F00_1.png:16:16]

I have changed electrodes to carbon one's.

But still it is no enough to power supply MCU. Here is example of start atmega328 with 128 kHz clock circuit with simple LED blink program. This salt water cell allow to supply this circuit for the while.
