Solar Radiation (Silicon Pyranometer) Smart Sensor

Product Options


Effectively measure light levels with this silicon pyranometer sensor. The Solar Radiation Smart Sensor enables rapid deployment. Since HOBO data loggers recognize this sensor, no complicated programming or setup is required. This product offers a measurement range of 0 to 1280 W/m2 over a spectral range of 300 to 1100 nm. A measurement averaging mode is available.

Also available in a wireless model for use with the HOBOnet Field Monitoring System.
