Relative Humidity (RH) Data Loggers & Sensors
Onset offers a selection of relative humidity data logging solutions, from stand-alone RH data loggers to external RH sensors that plug into external channels. Whether your RH data-logging application is indoors or out, find the solution you need below.
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 HOBO RX3000 or the HOBO MicroRX 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.
The HOBO MX2302 is a weatherproof data logger with external temperature and relative humidity sensors. Leveraging Bluetooth Low Energy, the logger enables easy, fast setup and data download directly from your mobile device or Windows computer with Onset's free HOBOconnect app. The MX2302 provides high-accuracy measurements in harsh outdoor environments.

Onset’s HOBO MX1102 CO2 logger makes it more convenient than ever to measure and record CO2 in buildings and other non-condensing environments. It measures CO2 from 0–5,000 parts per million (ppm) – and our free HOBOconnect app lets you access data right from your mobile phone, tablet, or Windows computer when within a 100-foot range of the logger.
The MX1102 also features a USB port so it can be used with a computer running HOBOware graphing & analysis software.
