Canada’s Instrumentation Leader Since 1946.
Measures light intensity for frequencies relevant to photosynthesis. HOBOnet wireless sensors communicate data directly to the HOBO RX3000 or the HOBO MicroRX station or pass data through other wireless sensors back to the central station. These sensors are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onset’s innovative cloud software platform.

The RXW-LIA-xxx sensor supports the following measurements: Light Intensity and PAR
HOBOnet Field Monitoring System
The NEW HOBOnet Field Monitoring System from Onset provides a cost-effective and scalable solution for web-enabled monitoring of field conditions for applications such as crop management, research, and greenhouse operations.
|Measurement Range||0 to 2500 μmol/m2/sec, wavelengths 400 to 700 nm|
|Accuracy||±5 μmol/m2/sec or ± 5%, whichever is greater in sunlight; Additional temperature induced error ±0.75 μmol/m2/sec/°C from 25°C (0.42 μmol/m2/sec/°F from 77°F)|
|Angular Accuracy||Cosine corrected 0 to 80 degrees from vertical; Azimuth Error <2% error at 45 degrees from vertical, 360 degree rotation|
|Drift||<±2% per year|
|Operating Temperature Range||-25° to 60°C (-13° to 140°F) with rechargeable batteries
-40 to 70°C (-40 to 158°F) with lithium batteries
|Radio Power||12.6 mW (+11 dBm) non-adjustable|
|Transmission Range||Reliable connection to 457.2 m (1,500 ft) line of sight at 1.8 m (6 ft) high
Reliable connection to 609.6 m (2,000 ft) line of sight at 3 m (10 ft) high
|Wireless Data Standard||IEEE 802.15.4|
|Radio Operating Frequencies||RXW-LIA-900: 904–924 MHz
RXW-LIA-868: 866.5 MHz
