Low-Cost Microcontrollers:
Applications for Small-Scale Agriculture
Tim Motis
Excerpt:
Think of a microcontroller as a tiny computer that does specific tasks, like reading a sensor every hour. Once programmed, the microcontroller and any sensors connected to it can operate apart from a computer. The usefulness of microcontrollers goes beyond data logging. Microcontrollers can perform actions triggered by sensor readings. You could turn on a heat source if temperatures drop too low or turn on a solenoid valve if soil moisture levels indicate that water should be applied to a garden or field.
