COMET U0110G – IoT Wireless Data Logger with 4G Modem and Internal Temperature Sensor

COMET U0110G – IoT Wireless Datalogger with 4G Modem, Internal Temperature Sensor (-20 to +60 °C ±0.4 °C), 500,000 Data Points Memory, SMS/JSON Alarm 

The COMET U0110G is a state-of-the-art IoT wireless datalogger with an integrated 4G modem (LTE Cat 1) – a fully autonomous and network-independent solution for remote monitoring and long-term temperature recording with its internal sensor. Whether for cold chain, warehouses, climate chambers, cold rooms, transport, server rooms, archives, offices, greenhouses or remote sites, the U0110G immediately sends SMS and JSON alarms via 4G when threshold limits are exceeded. Regular JSON data transmission to COMET Database or COMET Cloud (a complete monitoring, alarm, and analysis tool) is configurable. Local alarms are indicated by LED, LCD, and buzzer. With a memory capacity of 500,000 readings (non-cyclic) or 350,000 readings (cyclic) and a traceable calibration certificate (EN ISO/IEC 17025), it is the perfect device for quality management, audits, and temperature documentation.

The internal temperature sensor measures from -20 to +60 °C (±0.4 °C) with a resolution of 0.1 °C. The response time t90 is 15 minutes (for a 20 °C change at 1 m/s airflow). The acoustic and optical alarm instantly warns when adjustable limits are exceeded. Min/Max values are stored. The backlit LCD display provides clear visibility, and measurement and display update intervals can be set (1 s, 10 s, 1 min). The logger operates fully autonomously with a rechargeable Li-Ion battery A8200 (3.6 V / 5200 mAh) – no external power supply required. Data download to a PC is possible via USB-C. COMET Cloud access is free for 3 months, then 1 credit per year. The supported LTE FDD B1/B3/B5/B7/B8/B20 & GSM/GPRS/EDGE 900/1800 MHz modem ensures worldwide coverage and stable data transmission. The IP67 enclosure makes the device robust for harsh environments (dimensions with antenna 120 × 93 × 53 mm).

The datalogger is maintenance-free, long-term stable, and backed by a 3-year warranty. The included traceable calibration certificate guarantees high measurement accuracy from the factory. Configuration is intuitive via the LCD or COMET Cloud. Whether used as a mobile remote logger in transport vehicles, as a stationary monitor in rooms, or as a central device in facility management, the U0110G stands out for its precision, autonomy, 4G connectivity, and ease of use. No external probe required – ready for immediate indoor measurements.
