I want, for my very first project, to accomlpish the task of watering my lawn.
I attached a drawing, it is a basic Idea of what I would like to accomplish.
I am looking for any helpful info on this project, and would be very grateful.
you prob. I am also posting these posts in the "project guidance" section of the forums at
arduino.cc and allot of cool people are helping me out.
I have been experimenting with so many different sensor designs and I am going to go with the gypsm block sensor for now.
This is basically 2 wires encased in a plug of plaster of paris.
I realize the limitations of these sensors and if all goes well I will probably replace them with the vegetronix ones eventually.
so, I have wasted a week or 2 trying to figure out and build different sensors. \
ReplyDeleteUnderstanding that they are not the best choice, I am going to go with the gypsm blocks anyway.
mainly because they are the only one that I am recieving a reading high enough to set on/off limits to send a signal
to the valve. and the vegetronix are like $40 a pop.
the point I am at now is trying to figure out how to hook up 2 sensors to the arduino and get a serial read on them,
so that I can compare the 2 readings.
the 2 sensors are right now in my basement in a container of soil.
but I can only hook up 1 at a time.
The guys at arduino.cc have helped me out with the code and I now have 2 sensors hooked up.
ReplyDeletebut I am getting 2 wildly different readings from the same soil.
I have to get a consistant sensor.
