PAR sensor for HOBOnet network RXW-LIA-868

The wireless sensor measures'luminous intensity for frequencies relevant for the photosynthesis.
Wireless sensors HOBOnet communicate the data directly to the HOBO RX3000 or at the station HOBO MicroRX or transmit data via other wireless sensors to the central station. These sensors are preconfigured and ready for deployment, and the data are accessible via HOBOlink, the innovative cloud software platform of'Onset.

Important:

One complete system requires at least one remote monitoring station HOBO RX3000 , a wireless manager HOBOnet and a wireless sensor HOBOnet, OR a MicroRX HOBO station (which has an integrated HOBOnet wireless manager) and a HOBOnet wireless sensor.
Des wireless repeaters HOBOnet (RX-RPTR-xxx or RXW-RPTR-B-xxx ) can be added to extend the scope.

Technical characteristics of the sensor:

- Measuring range from 0 to 2500 umol/m2/sec on wavelengths from 400 to 700 nm
- Locked in an anodized aluminium case with acrylic diffuser
- Wireless features
- 900 MHz wireless mesh self-healing technology
- Wireless range from 450 to 600 metres (1,500 to 2,000 feet) and up to five jumps
- Up to 50 wireless sensors or 336 data channels per HOBO RX station
- Just press a button to join the HOBOnet wireless network
- Onboard memory to avoid data loss
- Powered by rechargeable AA batteries and integrated solar panel
