Designed for the HOBOnet Wireless Sensor Network, this wireless PAR sensor measures light intensity for frequencies relevant to photosynthesis. It features a range of 0 to 2500 umol/m2/sec over wavelengths from 400 to 700 nm.
Designed for the HOBOnet Wireless Sensor Network, this wireless PAR sensor measures light intensity for frequencies relevant to photosynthesis. It features a range of 0 to 2500 umol/m2/sec over wavelengths from 400 to 700 nm.
The photosynthetically active radiation (PAR) sensor is compatible with the RX weather stations. This measures the active radiation between 400 to 700 nm. The measured data are then transmitted wirelessly across the network to the central station to the HOBOlink web-based software where you can monitor sensor readings, view graphs, set up alarms, download data, and more.
