  • Cost effective measurement of relative humidity (RH)
  • Automatic sensor recognition and display of appropriate units
  • Broadens the range of experiments
  • Humidity sensor and DrDAQ both take their power from the PC -
    so no batteries required
  • Low cost Reed Switch (for timing applications) now also available
    for DrDAQ
  •   Library of FREE experiments available on the Web
  • PicoLog and PicoScope software supplied FREE with DrDAQ
 Pico Technology, specialists in PC-based
instruments, has announced the immediate availability of a low-cost humidity
sensor for its popular educational data logger DrDAQ. The sensor is designed
for the cost effective measurement of relative humidity (RH) in the range 20
to 90 percent RH and features a resolution of 0.2 percent RH and an overall
accuracy of +/- 10 per cent.

 

Operating in the temperature range 0 to 60 degrees C, the humidity sensor
plugs straight into DrDAQ (which requires no power supply) and the data
logger 'recognises' the humidity sensor. Readings are automatically
displayed in percent RH.

 

Mike Green, Managing Director of Pico Technology comments: "By adding
humidity measurement to DrDAQ's capabilities we've greatly increased the
number of science experiments that can be conducted in primary and secondary schools. These experiments are not only ideal for those courses/teachers aiming to deliver step-by-step tuition to science pupils, but also provide a foundation for courses where 'free-thinking' is encouraged."

Humidity sensing adds to DrDAQ's existing ability to measure and record
temperature, light levels, sound waveforms and sound level (dB) and -
through the use of plug-in sensors - external temperature and pH. Pico
Technology's experiments, FREE to download and written by science teachers
and industry experts, can be found at www.picotech.com/experiments/
 

"Although the experiments can be conducted using traditional, bench-top test

and measurement equipment, pupils often have limited access to such
equipment," continues Green. "Which is why we recommend the use of PC-based
(virtual) oscilloscopes and data loggers."

 

The results of the experiments can be observed on a large screen, printed,
saved to disk or even transferred over the school or college
intranet/internet.

 

"The humidity sensor can be used in a number of physics, chemistry and
biology experiments," notes Green. "And by combining the use of the humidity
sensor with DrDAQ's existing sensors, it's now possible to perform data
logging and measurement experiments that require a number of parameters to
be monitored simultaneously."

Low-cost Reed Switch
Pico Technology has also announced the immediate availability of a low-cost
reed switch sensor for DrDAQ that can be used to detect the presence of a
magnetic field from, for example, bar or electro- magnets.
The reed switch's response time is 2ms, so it makes an ideal low cost
alternative to light gates for timing and acceleration studies. In addition,
through PicoLog data logging software the reed switch's condition
(open/closed) can be averaged over time; for example to generate a
percentage figure of how frequently a particular door in the school is
opened/closed.

 

"The Reed Switch lends itself well to timing and statistical applications,"
concludes Green, "and can be used in a number of physics and general study
experiments."

 

DrDAQ
DrDAQ takes its power from the PC to which it is connected (via parallel
port) so there is no need for separate power supplies.

The DrDAQ board features built-in sensors for light, sound waveforms, sound
level, temperature, voltage and resistance. In addition, a socket accepts
any standard pH electrode. There are two sockets for a range of optional
external sensors such as humidity, pressure and magnetic field.

 

DrDAQ recognises the presence of external sensors and automatically scales
and calibrates all readings.

 

The PicoScope and PicoLog software packages referenced above are compatible
with Windows 3.1x, 95/98/ME and NT/2000, and are supplied FREE with DrDAQ.
