HOBONode Wireless Temperature & Soil Moisture Sensors
HOBOnode wireless sensors monitor temperature and soil moisture conditions and transmit the data back to your computer. They enable you to view current conditions through a remote sensor, receive alarm notifications, and log data on your PC without having to run cables through the field.
Key Advantages of Using Remote Sensors:
Sensors transmit current field conditions to your PC
Accompanying software provide audible and visual alarm notifications
Up to 9km transmission range (with HOBOnode Repeaters)
Sensors can be easily added to a HOBOnode network
Ideal for frost alarms, agricultural research, crop management, and more.
System consists of:
1. Wireless Sensors (up to 50):
Temperature - (W-TMB)
Soil Moisture - (W-SMC)
2. Wireless Base Station
3. Software
HOBO Node Viewer Software (Free)
Optional HOBOWare Pro Software
4. Optional Repeater Stations to extend tranmission range
Specifications
Temperature - Range: -40° to 100°C; Accuracy - 0.22°C from 0 to 50°C; Resolution - 0.025° at 25°C (Note: For accurate temperatures in sunlight we recommend the use of a solar radiation shield. (RS3))
Soil Moisture - Range:0 to 100% volumetric water content; Accuracy - 3.1%; Resolution - 0.07%
Sample rate -1 reading per minute
Battery life - 1 yr typical w/o charging; 3 yrs typical w/ solar charging
Transmission range - HOBOnodes to receiver or repeater: 420m (1400') with clear LOS; 300m (1000') typical
Wireless Data Standard - IEEE 802.15.4, 2.4 GHz ISM band (license free worldwide)
Environmental rating - HOBOnodes: NEMA 6P, IP68; temperature sensor probe is rated for 1-year immersion in freshwater ≤ 50° C
Setup/Installation - recommend PVC pipe for mounting; the HOBOnodes should not be mounted on metal poles.
NOTE: These sensors do not have an internal datalogger. Critical applications require a PC with backup power supply to ensure no loss of data or alarming.
