Temperature/Light/Sound Sensor
NOTE
: The Temperature, Light, and Sound Sensors
are not calibrated and cannot be calibrated within
PASCO software
This 3-in-1 sensor records ambient temperature,
brightness as a measure of relative light intensity, and
loudness as a measure of relative sound level.
•
The temperature sensor measures ambient
temperature between 0
– 40 °C.
•
The light sensor measures brightness on a 0
–
100% scale, where 0% is a dark room and 100%
a sunny day.
•
The sound sensor measures loudness on a 0
–
100% scale, where 0% is background noise (40
dBC) and 100% is a (very, very) loud scream
(~120 dBC).
Magnetic Field Sensor
The magnetic field sensor only measures the strength of
a magnetic field in the y-axis. A positive strength is
produced when the north pole of a magnet it moved
towards t
he “N” in the magnetic field sensor icon on the
//code.Node.
While the magnetic field sensor cannot be calibrated in
the software application, the sensor measurement can be
tared to zero.
Button 1 and Button 2
Button 1 and Button 2 are included as basic momentary
inputs. While pressed the Button will be assigned a value
of 1. A value of 0 is assigned when the button is not being
pressed.
Acceleration Sensor and Tilt
The acceleration sensor within the //code.Node measures
acceleration in the x- and y- axis directions, which are
labelled on the sensor icon shown on the device. The
pitch (rotation around the y-axis) and roll (rotation around
the x-axis) are measured as Tilt Angle -x and Tilt Angle -
y respectively; the tilt angle is measured to a ± 90° angle
in relation to the horizontal and vertical planes.
The acceleration and tilt angle measurements of the
sensor can be tared to zero from within the software
application
When placed face-up on a flat surface, tilting the
//code.Node left (thus rotating around the y-axis) will
result in a positive x- acceleration and a positive x- tilt
angle up to 90°. Tilting to the right will result in a negative
x- acceleration and negative x- tilt angle. Similarly, tilting
the device upwards (rotating around the x axis) will result
in a positive y- acceleration and positive y- tilt angle to a
max angle of 90°; tilting the device downwards will
produce negative values.
