HOBOnet多深度土壤湿度传感器
Discontinued
$800.00 USD
一款获奖的无线传感器，可与HOBOnet系统配合使用，通过单个探头测量多个深度的土壤湿度和土壤温度，实现快速简便的安装。
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 无线管理器以及一个HOBOnet 无线传感器，或者一个HOBO MicroRX 站（集成了 HOBOnet 无线管理器）以及一个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
一款屡获殊荣的无线传感器，与HOBOnet系统配合使用，通过单个探头测量多个深度的土壤湿度和土壤温度。安装快速简便，这款耐用的传感器和3段式探头可测量至45厘米（18英寸）的深度。
采用GroPoint的TDT5技术和专利天线设计，该传感器可沿每个探头段的整个长度测量土壤湿度，从而使每个测量段具有最大的影响体积。每次测量的高频脉冲可提供精确且一致的土壤湿度数据。
我们建议使用可选的导向杆和滑锤以实现快速简便的安装，PILOT-ROD4（28英寸）适用于RXW-GP3。
HOBOnet系统是一种经济高效且可扩展的无线传感器网络，用于基于网络的田间条件监测，适用于作物管理、研究和温室运营等应用。由于它是无线的，您可以部署传感器网络，通过单个系统轻松监测多个点，同时避免长电缆可能干扰田间作业的风险。传感器可轻松连接到网络，数据可通过Onset创新的云软件平台HOBOlink®访问。
型号RXW-GP4-xxx和RXW-GP6-xxx（4段和6段探头）已不再供应。如有任何疑问，请联系销售。

FAQs
For fast and easy installation, with minimal soil disturbance, a pilot rod and slide hammer may be used. An auger may also be used to create a hole for the soil moisture probe. Consult the user manual (in the documentation tab) for more details.
These sensors come factory-calibrated for use in most soils. They can, however, be calibrated for specific soils.
The GroPoint user manual provides instructions on how to perform soil-specific calibration using a GP-USB Connect SDI-12 programming tool (available from https://www.gropoint.com/). Refer to Appendix A of the GroPoint manual, available at https://www.gropoint.com/products/soil-sensors/gropoint-profile/ from the Downloads tab.
These sensors are intended to have the top of the probe near the surface of the soil with the length of the probe determining the lowest depth of the soil moisture and temperature points.
