U3631M IoT wireless temperature and relative humidity data logger for external sensor, built-in GSM modem COMET

Description

U3631M IoT wireless temperature and relative humidity data logger for external temperature and relative humidity sensor (known as a probe) with built-in GSM modem.

In case the set limits are exceeded, you can set up SMS and JSON notification messages over the GPRS data connection. The measured values can be sent to the COMET Cloud, a complete monitoring, alarm and analysis system.

It is also possible to configure the regular sending of JSON messages to the COMET database, the sending interval is configurable. Alarms are displayed locally by LED, LCD and audible signal with built-in beeper. You can transfer the data to your computer via the included USB-C cable.

The GSM recorder shall include a calibration traceability certificate with declared metrological traceability of standards based on the requirements of EN ISO/IEC 17025.
