COMET W0911 – LoRaWAN Temperature Sensor for External Pt1000 Probe – 90 to +260 °C

COMET W0911 – Battery-powered LoRaWAN Temperature Sensor for External Pt1000 Probe, –90 to +260 °C    

The COMET W0911 is a robust, battery-powered LoRaWAN temperature sensor for external Pt1000 probes – the perfect IoT solution for wireless, energy-efficient remote monitoring in industry, storage, cold chains, greenhouses, technical rooms, or anywhere wiring is costly or impossible. With a measuring range of –90 to +260 °C and battery life of up to 10 years (depending on interval), it is ideal for long-term applications in harsh environments.

The sensor uses an external Pt1000 probe (sold separately or included depending on configuration) and measures with high accuracy (±0.2 °C from –90 to +100 °C; ±0.2 % of reading above that). Measured values are transmitted wirelessly via LoRaWAN (Europe 863–870 MHz) at adjustable intervals (5 min to 24 h) to the COMET Cloud – where charts, exports, alarms, and remote configuration via app or web browser are available. Two configurable alarm limits with push notifications protect against critical temperatures.

The IP65 enclosure protects against dust and water jets – ideal for outdoor or humid environments. The integrated, replaceable battery lasts 3–10 years depending on the transmission interval. No wiring, no power connection required – simply mount and start measuring. The COMET Cloud is included for 1 year free of charge (then 1 Credit/year), including data storage and alarm functions.

The W0911 is maintenance-free, long-term stable, and supplied with a traceable calibration certificate (according to EN ISO/IEC 17025) – top quality for critical monitoring applications. An optional preconfigured LoRaWAN gateway is also available – ready for immediate Cloud integration.

Installation & commissioning – done in minutes

Mount the sensor, place the Pt1000 probe at the desired location, insert the battery, ensure LoRaWAN network (gateway) is within range – done! Activate and configure via COMET Cloud – no wiring, no programming required.

Summary:

  • The W0911 sensor with LoRaWAN network interface measures temperature via an external Pt1000 sensor on cable and can be installed directly in the measurement environment thanks to its IP65 housing.
  • LoRa devices are powered by a replaceable battery with a service life of up to 10 years (3 years standard).
  • Measured values are wirelessly transmitted to COMET Cloud storage at adjustable intervals (from 5 minutes to 24 hours) and are available to users via computer or mobile device.
  • The sensors allow remote configuration via COMET Cloud and can monitor up to two alarm thresholds.
  • When a threshold is exceeded, a notification is sent to the user.
  • Wireless transmission of measured values and alarm states. Battery-powered with low battery indication (battery life up to 10 years).
  • Remote configuration of the device via COMET Cloud.
  • Protection class IP65.
  • Calibration certificate with declared metrological traceability of standards according to CSN EN ISO/IEC 17025.
  • When purchasing a new wireless sensor with LoRaWAN connectivity, COMET Cloud is included free for 1 year; one Credit is required for each additional year of use in COMET Cloud.
  • The sensor comes preconfigured for COMET Cloud.
  • If you wish to connect it to your own cloud system, please specify this when ordering.
  • Only then will you receive the required access credentials.
