The SparkFun Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and similar materials. The soil moisture sensor is pretty straight forward to use. The two large exposed pads function as probes for the sensor, together acting as a variable resistor.
It can be used by journalists to collect data for stories about agriculture or weather. Also, it can be connected to an auto watering system. It helps to determine when and how much to water and may help save water and energy. It can be used at home or for the plants in public area. In addition, I think it may be able to used in food processing as well. Some food need certain level of moisture to be right. The moisture sensor can supervise that.
