27 and convert to volumetric water content. Write hourly

average to datalogger final storage.

3 Read datalogger battery voltage and 3 CS616s hourly. Convert

CS616 period to volumetric water content. Write average of

hourly readings to final storage every 4 hours.

4 Measure soil temperature and CS616 output period every 4

hours. Correct CS616 output period for temperature and write

result to datalogger final storage.

5 Hourly, measure datalogger battery voltage, internal temperature

and 48 CS616 probes using AM16/32 multiplexer.
