Sensors

Battery Powered (incl. lithium batteries)

A battery-powered wireless sensor that works with the HOBOnet system to monitor air temperature and relative humidity.

Important Information

Includes lithium batteries. A complete system requires a HOBO MicroRX Station, which has an integrated HOBOnet Wireless Manager, and a HOBOnet Wireless Sensor. HOBOnet Wireless Repeater (RXW-RPTR-B-xxx) can be added to extend the range of both system options.

Overview

A cost-effective and scalable solution for web-enabled monitoring of air temperature and humidity. HOBOnet wireless sensors communicate data directly to the 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.

Resolution	0.02°C (0.036°F)	0.01% RH
Drift	<0.01°C (0.018°F) per year	<1% per year typical
Response Time (typical, to 90% of change)	3 minutes, 45 seconds in air moving 1 m/s	15 seconds in air moving 1 m/s
