Wireless Farm monitoring system

Three inputs being the main sensors are connected to the microcontroller, PIC 16F877 which feeds information into the RF 315 MHz transmitter and receiver which is connected wirelessly to the USB on the computer through another microcontroller. The output is shown on a Microsoft excel page. Feedback is given by the computer and is transmitted wirelessly back until the microcontroller orders the sprinklers to irrigate. We explain further on each process being; input, process and the output
