Description

The W7910 sensor with LoRaWAN network output measures temperature, humidity, and atmospheric pressure using integrated internal sensors and can be installed directly in the measurement environment thanks to its IP65-rated housing. LoRa devices are powered by a replaceable battery with a lifespan of up to 10 years (3 years standard). External power is also available with optional accessories. The sensor can be used with a suitable cover even in more demanding conditions.

Measured values ​​are transmitted wirelessly at adjustable intervals (from 5 minutes to 24 hours) to COMET's cloud storage, where users can access them via a computer or mobile device. The sensors are remotely configured from the COMET cloud and can monitor up to two alarm thresholds; any exceedance is notified by an alert sent to the user. Key Features

Wireless transmission of measured values ​​and alarm statuses
Battery-powered with a low-battery indicator (up to 10 years of battery life) and an external power supply option
Remote device configuration via COMET Cloud
IP65-rated housing
Calibration certificate with metrological traceability declared according to CSN EN ISO/IEC 17025 standards
A pre-configured gateway is available as an accessory at an additional cost. For ease of use, we offer the pre-configured LoRaWAN SP041 gateway, fully prepared for communication with COMET Cloud and our sensors. This option simplifies the configuration process and saves users time.
