iButton Hygrochron Temperature/Humidity
Logger with 8KB Data-Log Memory
ABSOLUTE MAXIMUM RATINGS
IO Voltage Range Relative to GND ..........................-0.3V to +6V
IO Sink Current....................................................................20mA
Operating Temperature
and Humidity Range ................-20°C to +85°C, 0 to 100%RH*
Storage Temperature
