W0841 IoT wireless temperature sensor for 4 Pt1000 external temperature sensors with ELKA connector, Sigfox COMET

Description

W0841 IoT wireless temperature sensor measures temperature from four external Pt1000 temperature sensors (probes) on an ELKA cable, providing high protection IP 65.

The measured values are sent at a configurable time interval (10 min to 24 hours) via radio transmission over the Sigfox network to the COMET cloud, from which the user can view them using a PC or mobile device.

The instrument can control up to 2 alarm limits for each measured temperature channel. You will be alerted if you exceed these limits by a message sent to you. COMET Cloud sends this alarm message to the selected user by email. The device is suitable for applications that allow a delay in the information provided by Sigfox (maximum 10 minutes).

 

Benefits of W0841

• wireless transmission of measured values and alarm status
• temperature measurement at up to four locations for the price of one subscription
• remote device setup possible from COMET Cloud (up to once per day)
• Protection class: IP 65
• availability of the Sigfox network in certain areas

Before buying a device, check the availability of the Sigfox network. COMET devices on the Sigfox network can be used anywhere in the RC1 area. Read more about Sigfox Radio Zones (RC).
