This project is a Moisture Sensing Hydro-Dispenser. It is made from an arduino, solenoid valve, moisture sensor, wires and other simple and relatively cheap electrical components (diodes, transistors and resistors). It's basic task is to measure the soil moisture level at a given location before adding a certain amount of water for the plant life of that area.It will read the moisture content of the soil and depending on this reading turn on the water supply. Once the ideal moisture content has been reached, to turn off the water supply.
It is composed of a microprocessor (Arduino) that uses a sensor( Soil Hygrometer sensor) to sense the moisture level of the soil before turning the sprinklers on or dispensing water. The moisture content/level in the soil is the ratio of water to soil any given time. The Soil Hygrometer sensor has two prongs that are immersed in the soil. One of the prongs sends an electrical pulse through the soil. The other prong receives some, all or none this electrical pulse. Depending on the amount that is transmitted through the soil, the Arduino/ Microprocessor receives a certain reading. Since water is a better conductor than soil, the value the Arduino receives is going to be different depending on the amount of water in the soil.
This project is a product of engineering expertise and top notch creativity. The fact that it is also built from relatively cheap parts makes it ideal for farmers or even plant owners who are too busy to water their plants. On a global scale it might be used for wide scale conservation of water.
This is a basic sketch of the project and modifications will be made through out the building process.

Good overview of project. Be sure to be objective and use the third person, no personal pronouns like I, we, our, my, you, etc.
ReplyDeleteThe abstract says the arduino senses the water level. Be more specific, what kind of sensor are you using?
