Product Description
Onset HOBOnet Temp Sensor - RXW-TMB-900
Overview
The HOBOnet Wireless Temperature Sensor provides a cost-effective and scalable solution for web-enabled monitoring of air, soil and water temperatures. HOBOnet Wireless Sensors communicate data directly to the RX3000 weather station or pass data through other wireless sensors back to the central station. They are preconfigured and ready to deploy, and data is accessed through HOBOlink, Onsets innovative cloud-based software platform.
