RD01-example-program

This program shows how to read the sensor with a Campbell Scientific data logger by measuring the analogue signal, the rain on/off state, and the MODBUS outputs. The program scales the sensor output to give a value between 0 (dry) and 100 (heavy rain) and returns a true/false value for whether it is raining or not. To determine the rain on/off state, a 10 k resistor must be placed between the control port where the rain on/off wire is attached and 5 V on the data logger.
