HOBO MX2301A Wireless Temperature and Humidity Data Logger - Optional Remote Monitoring
The HOBO MX2301A is a weatherproof data logger with built-in temperature and relative humidity sensors. View current data in real time with the free HOBOconnect app. Add near real-time cloud-based monitoring (see options below).
Communications
Access your data directly from your mobile phone, tablet or Windows computer when within 100 foot (30 m) line-of-sight range of the logger, with the free HOBOconnect app.
To enable cloud data storage and analysis, add an MX Data Plan (select from the options above).
To enable near real-time remote monitoring and alerts via email or text message, add an MX Data Plan and an MX Gateway (select from the options above). Note: the MX Gateway must be indoors.
