TagTemp Temperature Datalogger

Description

 

The TagTemp is a small low-cost portable temperature datalogger. Its' internal sensor measures local environmental temperatures and logs readings in internal memory. Logged data can be later viewed and analyzed on a PC in both tabular and graphical forms. A unique feature of the TempTag logger is the built-in infra-red communication interface, leaving behind cables and accessories. Through this IR interface, the user can easily configure the application and download stored data from the logger to, for example, portable devices compatible with Palm-OS or Windows

Description

 

The TagTemp is a small low-cost portable temperature datalogger. Its' internal sensor measures local environmental temperatures and logs readings in internal memory.

The LogChart-II software is provided with the TagTemp and is intended for configuring the logger parameters (start/stop, log interval etc) and is also the tool used for analysis of the logged data. The data can also be exported to other applications such as Excel.

The communication between the PC and the TagTemp is taken care by either an RS232 or USB IR interface.

 

LogChart Software

 

The TagTemp is configured using the included LogChart-II software. Data is transmitted to the Penguin through an Infrared wand connected to the PC's RS232 or USB port. The Parameter Configuration window in LogChart lets you configure the following parameters:

  • Title - Instrument or process name

  • General Information - shows logger ID and status
  • Channel 1 and 2
    • Tag - defines a channel name
    • Type - temp or Humidity
    • Value - defines the way data is to be logged - instantaneous, mean (of 10 samples) Max/Min
    • Unit - either °C or °F
    • Alarms - Temperature only - Hi and LO alarms set LED blinking
  • Log rate - from 1 second to 18 hours
  • Start Logging options
    • immediately
    • Palm command
    • Start button
    • Date/time
  • Stop Logging options
    • At full memory
    • wrap around - logging never stops
    • After a set number of samples
    • Date/time

After the logging session is complete, data can then be downloaded again by LogChart and displayed in table and chart formats. Data files can then be saved as ASCII text files for importation into common Spreadsheets.

 

Palm PDA Users

 

Most of the functionality of the LogChart II is available for the PDA Palm running the LogChart PalmOS software. The program is supplied with the logger. The program is installed on the Palmtop through a HotSync process (data synchronization between a Palmtop and a PC).

Starting the LogChart PalmOS application will display the Recorded Data screen on the Palm where it is possible to access the LogBox configuration to change settings and collect data, as well as to access collected data.

HotSync of data stored in a PDA to a PC is performed through a conduit installed together with the LogChart Palm-OS. The conduit converts the data collected by the LogChart Palm-OS to a file compatible with the LogChart-II software.
