hi every one
i am doing a finall project
my project consiste of temperature sensor and soil sensor ,lcd and wter valve.
the soil sensor connected to comprater then to the micro 8051.
the temp sensor connected to a non inverting amp and then to the 8051.
the project should work as follows: at a certen time the the water valve will open and it will stay open untel the soil sensor get wet and then it will check for the temp range for example if 45 mintes it will keep the valve open for 5 mintes extra and so on and then it will close the valve and wait for the next time to start watering.
the question is i need to make a circuit to the water valve and program ON and OFF and i added two sitches to set the time by the way i am using assimbly language
sorry for the long story but i thought it is good to understand what is going on and thanks.
