Now available from Audon Electronics is the DLP-TH1,
a USB-based temperature and humidity sensor.
The DLP-TH1 sensor is supplied with free Windows software
that displays temperature, humidity, and dew-point data in
both Celsius and Fahrenheit scales, plots data graphically
to the screen, and logs to an Excel compatible data file on
the hard drive.
The software will also send an email to user-specified recipients if
the temperature or humidity exceeds specified alarm setpoints.
The DLP-TH1 sensor uses a fully calibrated capacitive polymer
sensing element for relative humidity with a 0-100% range and
a bandgap temperature sensor providing excellent long-term
stability with a -40° to + 120°C range. Calibration coefficients
for the sensors are permanently stored in digital memory within
the DLP-TH1 module so that the module is fully interchangeable
with any other DLP-TH1 module.
The DLP-TH1 is shipped with Windows 98/ME/2000/XP compatible
software and USB drivers and there is also an ActiveX and
LabVIEW VI's. No external power source is required as all power
is taken from the USB port via the provided 2M USB cable. Up to
20 DLP-TH1 sensors can be connected to a single PC through
USB hubs. Typical applications include monitoring temperature
and humidity in Server/Host rooms, hydroponics labs and
greenhouses and museum display cabinets.
