PASPORT Ultraviolet Light Sensor - PS-2149

Move to Wireless!

Recommended Alternative — The Wireless Light Sensor can perform all of the functions of the PASPORT Ultraviolet Light Sensor and long-term UV data can be logged directly onto the sensor. Wireless Light sensor supports visible light sensing, color detection as well as UVA, UVB and UV index measurements. Best of all, it connects directly* to your computers, tablets, smartphones and Chromebooks without the need for an interface and with no cables to get in the way.

*Devices without native Bluetooth® Smart connectivity will require a low cost USB adapter - see the product pages for details.



The Ultraviolet Light Sensor employs a narrow pass filter to measure the UVA band (315 nm - 400 nm). With the UVA filter removed, the sensor detects the visible as well as the UVA. The sensor includes the UVA filter, a collimator, and a sensor handle.
