U4440Msim IoT wireless data logger for temperature, relative humidity, CO2 and atmospheric pressure, built-in GSM modem and SIM card COMET

Description

U4440Msim IoT wireless data logger for temperature, relative humidity, CO2 and atmospheric pressure with built-in GSM modem and SIM card.

The data logger allows you to be notified by email if the set limits are exceeded. 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 audibly with built-in beep. 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.
