B.1.1 Example CR200(X) Program
This example program shows the measurement of a single CS215 and can be
used directly with CR200(X) series dataloggers.
'CR200(X) Series Datalogger
'Program measures one CS215 sensor every 30 seconds and stores the average
'temperature and a sample of relative humidity every 10 minutes.
