U4440Gsim Internet of Things Wireless Temperature, Relative Humidity, Carbon Dioxide and Barometric Pressure Data Logger with Built-in 4G Modem and Fixed Fee SIM Card

U4440Gsim
The IoT Wireless Data Logger Kit comes with a built-in GSM modem and fixed-fee SIM card for instant connection to COMET Cloud.
The IoT Data Logger is designed to record temperature, humidity, atmospheric pressure and carbon dioxide via built-in sensors. If set limits are exceeded, an email is sent from the COMET Cloud.
Alarms can also be displayed locally via LEDs, LCDs and the built-in buzzer.
Recording takes place in a non-volatile electronic memory. Data can be transferred to a computer via the included USB-C cable.
The device includes a traceable calibration certificate and declares that the calibrator's metrological traceability is based on the EN ISO/IEC 17025 standard.
Warranty: 3 years
