LI-1500 Light Sensor Logger
Intuitive, menu-driven interface
The menu-driven interface is easy to use. Attach
your LI-COR light sensor(s) to the three BNC con-
nectors. Log manually or use menus to set up one-time,
daily, or continual measurement routines. Sampling rates
and logging intervals are user-selectable.
Fast measurements (up to 500 Hz)
Use the LI-1500 with one sensor to sample and log
measurements up to 500 Hz – fast enough to meas-
ure the flicker rate of fluorescent, iridescent, incandescent,
and LED light bulbs. Graph these large data sets on your
computer using LI-COR’s FV7x00 software. Also view real-
time light measurements, GPS data, and other variables on
the eight-line display screen. Sample and log up to 20 Hz
with two or three sensors at once.
Global Positioning System (optional)
The LI-1500 features an optional global pos-
itioning system (GPS) for recording the location of
measurements. The GPS facilitates repeated visits to the
same location for tracking light levels over time. Log GPS
data independently or with light data.
Large memory capacity (1 GB)
With one gigabyte of flash memory, the LI-1500
stores a large amount of data on an internal SD
card. Also store configurations and up to 100 sensor-specific
calibration coefficients for later use. Enter the calibration
coefficient (multiplier) and date of last calibration just once.
When attached to a computer, the LI-1500 acts as a mass-
storage device with a simple drag-and-drop file system. Trans-
fer logged data to a computer with the included USB cable.
Data are formatted for easy import into widely used spread-
sheet and database software. Also transfer configurations and
sensor calibration data to a computer, and then share with
other LI-1500 units.
Weather-resistant, handheld
operation
The LI-1500 features a rugged housing and compact design
suitable for handheld outdoor use. The LI-1500 is powered
by four AA batteries, providing over 80 hours of operation
with typical usage, or 30 hours with the GPS option turned
on. Power can also be supplied from an AC wall outlet with
the provided USB AC to DC adapter. AC adapter plugs for
worldwide use are included.
Connects to LI-COR terrestrial and
underwater light sensors
Use the LI-1500 with LI-COR sensors to log pho-
tosynthetically active radiation (PAR), global solar radiation,
and light (the visible spectrum). Connect up to three
sensors at the same time. For instance, use two PAR sensors
to measure incident radiation above and below a plant can-
opy. You can also measure PAR along transects under a
plant canopy.
The LI-1500 features a built-in math function for measuring
vertical attenuation using two underwater PAR sensors. The
three input ports also allow for the measurement of incident
PAR above water while measuring simultaneous upwelling
and downwelling PAR below water.
