Appendix B. Example programs
The following examples are for the CR6 data logger. Other data loggers are programmed
similarly.
CRBasic Example 1: CR6 program measuring the EE181
'Program measures EE181 with single-ended inputs once every 5 seconds
'and stores the average temperature and a sample of the relative
'humidity every 60 minutes.
