RXW Wireless Temp Sensor, Indoor environments
Wireless Temperature Sensor for indoor environments
The HOBOnet Wireless Temperature Sensor provides a cost-effective and scalable solution for web-enabled monitoring of air temperature. HOBOnet wireless sensors communicate data directly to a HOBO RX 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, Onset’s innovative cloud-based software platform.

In what environment does this sensor operate?
This sensor operates in an indoor environment.
What measurements does this sensor support?
The RXW-TMB-x-xxx sensor supports the following measurements: Air Temperature, Soil Temperature, Temperature and Water Temperature
A complete system requires at least one HOBO RX3000 Remote Monitoring Station, a HOBOnet Wireless Manager (RXMOD-RXW-xxx), and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeaters (RX-RPTR-xxx) can be added to extend the range.
