RXW-THC-868 - HOBOnet Temperature & Relative Humidity Sensor

The HOBOnet Wireless Temperature and Relative Humidity Sensor provides a cost-effective and scalable solution for web-enabled monitoring of air temperature and humidity. 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, Onset’s innovative cloud-based software platform.

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. Still, think you might need some assistance in choosing the best solution?
