The relationship between leaf wetness duration, air temperature, and relative humidity is well known. The immediate project goals are to build an inexpensive datalogger capable of:
1. Measuring air temperature, relative humidity, and leaf wetness at an accurate timestep.
2. Storing measurements on an SD card with an RTC date time stamp.
3. Having sufficient power resources and sleep power management to log at 10 minute interval for a month.
4. Resisting weather and animal related intrusions.
A near future goal is to connect this datalogger with a standard fog collector and log tips of its modified rain gauge tipping bucket.
