Humidity/Temp USB data logger
Configuration software
User-selectable alarm thresholds
LEDs indicate logger status
IP67 protection
This data logger measures and stores up to 16,382 relative humidity
and 16,382 temperature readings over 0 to 100% RH and -35 to +80°C (-31
to +176° F) measurement ranges. The user can easily set up the logging
rate and start time, and download the stored data by plugging the module
straight into a PCs USB port and running the purpose designed software
under Windows 2000, XP or Vista (32-bit only). Relative humidity,
temperature and dew point (the temperature at which water vapor present
in the air begins to condense) data can then be graphed, printed and
exported to other applications. The data logger is supplied complete
with a long-life lithium battery, which can typically allow logging for
a year. Status indication is via flashing red and green LEDs. The logger
is protected against ingress from water and dust to IP67 standard when
the plastic cap and seal are fitted. This is a popular part, normally
stocked in high quantity and suitable for new designs. Download the
latest version (v4.0) of the configuration and graphing software from

use of alarm LEDs
** This specifies the overall error in the logged readings, for
relative humidity measurements between 20 and 80%RH
*** This specifies the overall error in the calculated dew point,
for relative humidity measurements between 40 and 100%RH at 25°C
