Introduction
The PS-2106A Light Sensor measures illuminance in units
of lux. Illuminance is a measure of how much the incident
light illuminates a surface, and is the total luminous flux per
unit area. The lux is a lumen per square meter. The lumen
(Systeme International (SI) unit) is defined in relation to the
candela, one of the SI base units.
The sensor is designed to work with a PASPORT-compatible
interface (such as the UI-5100 850 Universal Interface) and
PASCO data acquisition software (such as PASCO Cap-
stone) to measure illuminance.
The sensor includes a sensor mounting stud that can be
screwed into the threaded hole on the side of the sensor. The
sensor mounting stud can then be attached to a support rod
using a clamp.
The Light Sensor has a three ranges which are represented
by the icons next to the range select buttons. The candle
range is 0 to 2.6 lux, the light bulb range is 0 to 260 lux, and
the sun range is 0 to 26,000 lux.
Setup the Light Sensor
•
Plug the sensor into one of the PASPORT input ports of
a PASCO PASPORT-compatible interface.
NOTE: If more distance is needed between the sensor and
the interface, plug the sensor into the included Sensor Exten-
sion Cable, and then plug the cable into the interface.
•
Start the PASCO data acquisition software.
Using PASCO Capstone Software
•
Click the “Hardware Setup” icon in the Tools palette to
open the “Hardware Setup” panel. Confirm that the
Light Sensor icon appears with the interface’s icon.
