HOBOnet 叶片湿度传感器
Important Information
一个完整的系统至少需要一个HOBO RX3000远程监测站、一个HOBOnet无线管理器和一个HOBOnet无线传感器,或者一个HOBO MicroRX监测站(集成了HOBOnet无线管理器)和一个HOBOnet无线传感器。HOBOnet无线中继器(RXW-RPTR-xxx或RXW-RPTR-B-xxx)可添加以扩展范围。
Overview
为各种种植和研究应用提供准确的叶片湿度数据。这款预配置、即插即用的传感器无需涂漆或涂层,采用电容网格,与电阻网格传感器相比,对表面残留物的敏感度更低,并且经过预处理,可确保长期稳定性和传感器间的一致测量。
HOBOnet无线传感器可将数据直接传输至HOBO RX3000或HOBO MicroRX站,或通过其他无线传感器将数据传递回中心站。数据可通过HOBOlink(Onset的创新云软件平台)访问。

Two AA 1.2 V rechargeable NiMH batteries powered by built-in solar panel or two AA 1.5 V lithium batteries for operating conditions of -40 to 70°C (-40 to 158°F)
-
With NiMH batteries: Typical 3-5 years when operated in the temperature range -20° to 40°C (-4°F to 104°F) and positioned toward the sun (see Deployment and Mounting), operation outside this range will reduce the battery service life
With lithium batteries: 1 year, typical use
