Comet Wireless And IoT Data Loggers

COMET IoT Dataloggers are supplied with a calibration certificate that ensures metrological traceability based on the requirements of the standard EN ISO/IEC 17025. The measured values can also be periodically sent as JSON messages to the COMET Database, with adjustable sending intervals. For alarms over set limits, they are indicated using LED displays or LCD screens locally and acoustically using a built-in beeper.

Optional external probes and multiple channels make the COMET Wireless Data Loggers suitable for a wide range of applications: from agriculture to healthcare. Rugged protection class design ensures long term usage in harsh environments and non-volatile memory guarantees secured data storage.

Users can analyse the data easily by using COMET Cloud software that has advanced data analysis and storage features. COMET internet of things Dataloggers are a must-have wireless datalogging device to improve the effectiveness of environmental monitoring of air quality.

Robust Data Storage and Analysis And Strong Build

Being able to store up to 500,000 values in non-cyclic logging mode inside IoT dataloggers means that there are no missing of the important data point. The recording intervals are flexible between 1 second and 24 hours and can be adjusted according to your requirement. Cyclic recording is also possible where only the most recent data need to be kept.

Comet wireless data loggers integrate seamlessly with COMET Cloud, a monitoring, alarm and analysis system all in one. This web- based solution allows you to access your data from anywhere, facilitating more analysis and better decision making.

Comet has built IoT data loggers for toughness, having various ingress protection rating making it possible to deploy them in rough environments. The Li-Ion battery supplied makes the performance long lasting while the compact and lightweight design makes them easily portable.
