HDT-171 Temperature & Humidity Datalogger

This datalogger module can be used to monitor humidity and temperature of a variety of applications. It measures and stores up to 16,000 relative humidity and 16,000 temperature readings over 0 to 100%RH and -40 to +70°C  (-40 to +158°F) measurement ranges. The unit is easily programmable allowing the user to easily configure the logging rate, high/low alarm and start-mode. The logged data is simply downloaded by plugging the module straight into a PC's USB port and running the purpose designed software under Windows 98, 2000, XP, or Vista.

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 with a long-life lithium battery, which can typically allow logging for a year. Status indication is via flashing Red /Yellow LED and Green LED.
