Go Direct
Pyranometer
(Order Code GDX-PYR)
The Go Direct Pyranometer
measures the power of
electromagnetic radiation in watts per square meter. It is sensitive to the near
infrared, visible, and UV ranges, where nearly all of the solar energy is
concentrated. It is great for experiments with solar cells and calculating their
efficiency. The sensor is weatherproof and has a dome-shape top to allow it to
work with a wide range of sun angles. The Pyranometer has a 5 m cable.
An ideal pyranometer measures the entire solar spectrum, 280 to 2800 nm.
However, about ninety percent of sunlight energy is in the wavelengths between
300 and 1100 nm. The Go Direct Pyranometer detects all of this energy.
The Go Direct Pyranometer is cosine corrected and is designed to maintain its
accuracy when radiation comes from different angles. The cosine response when
the sun is at 75° to the zenith is ± 5 percent. Zenith angles greater than 75°
contribute less than 3 percent of daily radiation.

Bluetooth Connection
1. Install Vernier Graphical Analysis
on your computer, Chromebook™,
or mobile device. If using
®
LabQuest , make sure LabQuest
App is up to date. See
www.vernier.com/ga for Graphical
Analysis Pro availability or
www.vernier.com/downloads to
update LabQuest App.
2. Charge your sensor for at least
2 hours before first use.
3. Turn on your sensor by pressing the
power button once. The LED will
blink red.
4. Launch Graphical Analysis or turn
on LabQuest.
5. If using Graphical Analysis, click or
tap Sensor Data Collection. If using
LabQuest, choose Wireless Device
Setup > Go Direct from the Sensors
menu.
6. Select your Go Direct sensor from
the list of Discovered Wireless
Devices. Your sensor's ID is located
near the barcode on the sensor. The
LED will blink green when it is
successfully connected.
7. Click or tap Done to enter data-
collection mode.
Charging the Sensor
Connect Go Direct Pyranometer to the included Micro USB Cable and any USB
device for two hours.
You can also charge up to eight Go Direct Pyranometers using our Go Direct
Charge Station, sold separately (order code: GDX-CRG). An LED on each Go
Direct Pyranometer indicates charging status.
