Don't Panic, It's Organic! Jump In Everytime

I know. You run and check every hour if there is some change... I recognize that more than well. :)

Wait until you get them going and stay away from it a few days and get home and see the jungle... :)
 
Short update - the 2 lady's look good - just the one in the front, doesnt want to germinate... I'm considering about setting another seed in a jiffy, just in case this one wont germinate...what do u think?

Go for a new one... Sry :(

sad, but okay - when i wait longer it would be a problem with the other 2 lady's - or?! (time in vegetation?)

And as I said yesterday - I tinkered a bit around and made my own wireless weahterstation for the tent ;) nothing special, but it works fine - the temp / humidity u see is from my workbench, not in the tent ^^

For those who are interested:

  • D1 Mini (ESP -12F, Model ESP8266MOD)
  • DHT 22 Temp / Humidity Sensor
  • Few wires
  • Standard grid hole PCB, two sided
  • And a bit of coding ;)

Did CraZysWeeD see this???
You two are a match

Haha ;) looks like

The neat thing is, u only need a smartphone usb power supply and a usb mirco cable ;)

Yeah, go for a new one but let the other one sit a while. You never know.

I will do !

How does the code look for the wifi instructions?

Here u go ;)
 
Btw u can write a lot more stuff in it, for example a power saving option...that the D1 is nearly off everytime, just awake, make a measurement and go to sleep again....

It might also be cool to "store" the data - that the D1 send this to a MySQL DB...then u also could do a graph to see it over the hole day / night .... I think that would be the thing I will add ;)

Crazy code. :) So the server is run by Arduino? And then u just point your browser to Arduinos ip? But how do you know Arduinos ip, is than printed out with serial then?

Crazy? Hmmmm no not really :D Yeah, the webserver is run by the arduino itself, u can get the IP from the Serial output or u just look in your router ^^


As I thought, the connector from the sensor are to small to fit good in the socket...so I made a proper socket for it ;) Now it goes into the tent and I will tinker the DB ;)
