DS1923
iButton Hygrochron Temperature/Humidity
Logger with 8KB Data-Log Memory
Step 2: Write the setup data to register page 1.
During the setup, the device needs to learn the follow-
ing information:
? Time and Date
? Sample Rate
? Alarm Thresholds
? Alarm Controls (Response to Conditional Search ROM)
? General Mission Parameters (e.g., Channels to Log
and Logging Format, Rollover, Start Mode)
? Mission Start Delay
The following data sets up the DS1923 for a mission
that logs temperature and humidity using 8-bit format
for both.
