General: Press the power button on the sensor to turn it on. Connect your sensor as described in the Getting Started instructions for...
The Light Sensor Holder Bracket is designed to securely position either the Light Sensor (LS-BTA) or Go Direct® Light and Color Sensor (GDX-LC) to the optics bench.
To attach the Light Sensor, attach the tube mount onto the base of the holder us...
The values 650 nm, 550 nm, and 450 nm refer to the peak wavelengths of visible light to which the color sensors respond. These wavelengths correspond approximately to red, green, and blue.

Yes, the channels are identified by their primary wavelength - 615 nm, 525 nm, and 465 nm. The color of the traces on the graphs correspond to the colors that are detected:
615 nm - red
525 nm - green
465 nm - blue
Interestingly, the color of trace...
The UV Index (or UVI) was originally created as a predictive tool for the public to get a sense as to how intense the UV rays from sunlight will be. The US National Weather Service model takes into account the predicted filtering from the ozone layer...
The power button for the Light and Color Sensor also turns on the white LED. In order to turn on the light, turn the sensor on by pressing the power button, waiting until the Bluetooth LED begins flashing (5 seconds) and then pressing the power butto...
There are two conditions that can cause this issue with the Vernier Optical DO Probe. If you are measuring the rate of photosynthesis in the lab using an artificial light source, it could be light contamination. If you are doing a field experiment or...
