Wi-Fi temperature and humidity recorder-alarm
APPLICATION
“bun HYGRO X” is a temperature and relative humidity
(RH) recorder and alarm system with an external sensor.
It is powered by 2 replaceable AA batteries for up to 10
years and connects directly to Wi-Fi.
More than an accurate meter and a reliable data logger,
“bun HYGRO X” is also a cloud-based alarm system.
All setting parameters like measurement intervals, upload
intervals, minimum and maximum allowed temperature,
and humidity thresholds can be set through a web-based
application on any platform. It sends out email and text
message alarms as soon as any parameter goes wrong. It
also provides access to the records history, graphs and
periodical reports. Its hardware and software installation
is very easy and does not require any specific tools or
applications.

*Upload temperature range is the ambient condition required for the device to stay fully operational. These
operations include being able to connect and sync with the cloud and send out alarms. However, device can still
continue recording the data in its internal memory while in Temperature measurement range.
*Depends on reading and upload intervals and environmental conditions. Battery life is more than 10 years in a
standard set up. (Standard set up is room temperature 20 °C measurement every 15 minutes upload every 48
hours).
