My project allows me to ignore my garden for weeks at a time, but that time is limited.
The limit came through the finest particles of dirt, which even after filtering clogged the drippers.
This project doesn't change the basic irrigation method, it remains gravity fed,
but it's now monitored and adjusted by an inexpensive computer.
The idea is simple!
A micro step motor taken from a discarded CD drive puts pressure on the hose,
blocking the flow of water to allow only individual drops to fall.
2 open wires held below the hose end create a short circuit with each drop,
this short can be counted by the PC and used to limit the drops per hour.
A moisture sensor built into the ground stake holding everything above ground measures the effectiveness of water penetration, the PC uses this info to base it's drip frequency on.
Add a regular maintenance schedule which tells the motor to open and directly close at
regular intervals to wash dirt deposits out and it becomes maintenance free.
Costs can be minimized through 3d printing and the use of discarded motors.
Rather than only a stake, a printed top could be added to keep moisture away from
working parts and/or hold a solar panel. Through the use of an IoT module cost is increased,
but cabling is eliminated.
Tomorrow I'll discuss the advantages of this project and how I would implement it.
