W0932 IoT wireless thermometer with three-channels, LoRaWAN network

The W0932 sensor with LoRaWAN network output measures temperature  temperature from the built-in sensor and from two external Pt1000 probes on the cable and can be installed directly in the measured environment thanks to its IP65-rated enclosure. LoRa devices are powered by a replaceable battery with a lifespan of up to 10 years (3 years standard).

Measured values are transmitted wirelessly at adjustable intervals (from 5 minutes to 24 hours) to the COMET Cloud storage, where they are accessible to users via computer or mobile device. The sensors offer remote configuration from the COMET Cloud and feature the capability to monitor up to two alarm thresholds, with any exceedance signaled by an alert sent to the user.

Key Features

  • Wireless transmission of measured values and alarm states
  • Battery-powered with low battery indicator (battery life up to 10 years)
  • Remote device configuration via COMET Cloud
  • IP65-rated enclosure
  • Calibration certificate with declared metrological traceability of standards according to CSN EN ISO/IEC 17025
  • Preconfigured Gateway available as an accessory at extra cost. For ease of use, we offer the pre-configured LoRaWAN Gateway, which is fully ready for communication with COMET Cloud and our sensors. This option simplifies the setup process and saves time for users

 

With a newly purchased wireless sensor with LoRaWAN connectivity, you receive 1 year of COMET Cloud for free; an additional year of operation in COMET Cloud then requires 1 credit.

The sensor is preconfigured for COMET Cloud. If you want to connect it to your own cloud, please state this in your order. Only then will you receive the necessary access details.
