We are working on two main parts of this project, 1) the sensor that will be placed in the pot/garden, and 2) the base unit that will calculate and display what the user needs to do.

The Sensor Circuit:

I designed this circuit so a picaxe chip could read the sensors and transmit the data to the base unit. This needed to be as small as possible so I kept that in mind when deciding on parts. A Picaxe is a type of microcontroller that is all on one chip and doesn’t need any other components to run. Picaxe is coded in basic over a serial interface.

Bonus points to those who realize that I switched standards partway through drawing that, school vs self-taught knowledge.

From that design I made a mockup on a breadboard to check everything worked.

The Sensor Code:

The code I designed to just read the sensor values then send them over serial where I will connect some sort of transmitter.

Fuzzy Stuff:

Our fuzzy system currently will give us a vague English word for different values, success. Shalom is still working on perfecting this then integrating it to an AI.

Goals:

My next goal is making the physical circuit and then making the wireless data transfer work.
