Program Description
1
Measure volumetric water content with 4 CS625 hourly. Store
average hourly readings to final storage every 4 hours.
2
Measure temperature with 109 probe and use the 109
temperature to correct the period for 1 CS625. Use standard
calibration equation to convert temperature-corrected period to
volumetric water content. Sensors are read hourly and average
water content and temperature are written to storage every 4
hours.
