what about checking the ph and ec levels

this is the next step of my project, but I have some note for this will update before weekend have to find in all my notes

 

here are some probe not to expensive

Im thinking of doing one myself sorta a diy aerogarden that will check ph and ec, water temps, turn light and fans and off i got mechanics of it all but the coding will be a issue for me

here, I find the project which is very well documented.
Unfortunately it's in Italian but google translate will help.

for programming it's very good to start with codes that have a lot of comments

Thinking on doing something like that with arduino or raspberry pi and upload all info to a web dashboard like this  to put my raised bed data..

 

planning on having:

Ambient temperature

Ambient Humidity

Ambient Pressure

Light 

 

soil temperature

soil humidity

 

is there a way to get the PH? i havent found a sensor for it

Sorry but that is for water ph, isnt it?

 

will it be any difference on measure SOIL ph?

soil pH is longer to correct than liquids. I think it's not worth it. 

otherwise the sensors for liquids work if you dilute half with distilled water.

I didn't saw any on Arduino but sure it can be connect to it

 

 

 

here is a list of some soil probes

HALO® Wireless Soil pH Meter https://hannainst.co...nt-hi12922.html

 

Bluelab Soil pH Meter https://bluelab-stag...s/soil-ph-probe

https://jsfiddle.net/vLtfr8eo/1/show/

here is a small utility to make special characters for LCD display

click on a glyph from the buttom lcd to upload in the pixel box and modify it or grt the code

 

for the moment there is only copy output that works
if you want to copy the lcd at the bottom click right button and copy
for the pixel array click once on a pixel and right click on the same to select copy

will update link soon when all thing work well

 

very simple to create animate screen icon

example for when the mist is on                      and battery charging

That is pretty cool. I'm trying to learn how to program. Still a beginner but I've created a raspberry pi python program that automates an aeroponic setup based on weather. you can see the code here

 

It uses a compressor made for airbrushes, a water container, an air atomizing nozzle and some 12v solenoids which are hooked up to the raspberry pi with a relay board and operated by the GPIO pins.

From testing I have found soil humidity sensor are not working really well and are not precise.

I use time based irrigation instead.

This is my problem with arduino components as general.. They do the job, but doesnt give the accuracy im looking for. 


My current arudino setup in the greenhouse is

2x  dht22 (1 indoor, 1 outdoor)
1x cytron shield for 2a motor ( I use linear actuator for window)

2x relay for heater and fan


Also got the raspberry pi listening for the web interface.

if you use the cheap humidity sensor

you have to stop the power to the sensor when it is not used.

there are more accurate sensors on the market, but I'm too poor to buy them
