Wireless thermometer, hygrometer, Sigfox IoT

The wireless sensor measures temperature and humidity from the built-in internal sensor. It features a simple, compact design and is positioned directly in the measured area.

Measured values are displayed on the display and are regularly sent, in an adjustable time interval from 10 min to 24 h, by radio transmission in Sigfox to COMET Cloud. After the emergence of a new alarm (or the extinction of an alarm in progress), an extraordinary alarm message is sent at the latest within 10 minutes.

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

Radio configuration zone RC1. More information about Sigfox Radio Configurations (RC).

Features

Applications:

Healtcare and laboratories - Monitoring of storage areas at temperatures up to -200 °C.

Industry and production - monitoring temperature and humidity in food, pharmaceutical, aerospace etc.

Production facilities and warehouses - Monitoring of storage conditions and production processes in the temperature range -200 ° C to + 600 ° C. Sending data to COMET Database or SCADA third-party systems.

Metrology - COMET sensors together with COMET radiationshields are the ideal basis for weather stations for long-term weather, climate and air monitoring.

Data centers, server rooms - Temperature and humidity monitoring, data center monitoring, RACK stands, including flood status reports, opening / closing of doors (windows), motion, smoke. SNMP monitoring, remote alarms by email and Syslog.

Building management - Our instruments which measure temperature, humidity, atmospheric pressure and CO2 are an integral part of these industry-leading solutions.
