All you need is peace of mind!

“bun hygro” or simply "bun" is a temperature and relative humidity (RH) recorder-alarm system. It automatically  measures temperature and RH at desired intervals, stores all records on its internal memory, and syncs them via Wi-Fi to a cloud-based application named LoggerMaster. It is powered by an internal ultralong-life battery (up to 20 years). Recording intervals can be flexibly adjusted from 1 minute to 2 hours, and upload intervals can vary from every minute to once a week.

As an alarm system, "bun" immediately uploads the records if the measured values exceed or fall below the user-defined limits, and then then notifies the user via e-mail and SMS.

All the records (logs) are always accessible through LoggerMaster web-based application on any platform.
