Creating a Soil Moisture Sensor
The project in this chapter explains how to use the analog and digital ports of Intel Galileo to create a very low-cost system that measures the moisture levels in the soil for home applications. This project was demonstrated in a Maker Faire in October 2013 in Rome, Italy and the purpose was to create a project with only $4.00, excluding the cost of Intel Galileo board.
To measure moisture in the soil, you simply measure the quantity of water in it. There are different kinds of sensors available in the market, including neutron moisture gauge sensors, frequency domain sensors, capacity ...
