U3121M External Temperature & Relative Humidity IoT Wireless Data Logger With Built-In GSM Modem

Category: 4G Temperature & Humidity

Brand: Comet

Quantity: In Stock



Description


GSM datalogger is designed to record temperature. In case of exceeded set limits, SMS and JSON messages can be sent via GPRS data connection. Measured values can be sent to the internet storage COMET Cloud, which is a complete monitoring, alarm and analysis system.

It is also possible to set the regular sending of JSON messages to COMET Database, the sending interval is adjustable. Alarms are also indicated locally by LED, LCD and acoustically by built-in beeper. The recording is performed in a non-volatile electronic memory. The data can be transferred to a PC via included USB-C cable.

The temperature and humidity probe is not included in delivery, probe of the appropriate length and design you can choose in optional accessories.

The device includes Traceable calibration certificate with declared metrological traceability of etalons is based on requirements of ISO/IEC 17025 standard.
