===== Rationale =====
Soil Moisture Sensors are commonly applied in agriculture, environmental science, and climate science to measure the water content in soils. Bad irrigation management decreases crop yields and quality, increases the requirement of  fertiliser, is costly, wasteful and time consuming. By collecting water content data,  irrigation systems can be efficiently managed as the practitioner understands the loss of water from the soil caused by evaporation and plant uptake.

When water is poured into soil it fills the air space between soil particles. The sensor buried in the soil, measures the percentage of water to the percentage of soil present. Water retention within the soil can vary depending on the soil texture, environmental temperature, amount of organic contents and the type of crops. 
 
Night Owl, Foundation University (FU) based Arts and Technology incubator, began developing this project to assist the campus grounds keepers and improve FU’s agricultural production. The sensor is mounted onto a robot arm that is used to penetrate the soil. All components of the arm mechanism have been produced using a 3D printer. Movement of the robot and the sensor arm is controlled by micro-controller to connect all motor parts to the vex controller.
