W8810 IoT wireless temperature and CO2 sensor, Sigfox COMET

Description

W8810 IoT wireless sensor for measuring temperature and CO2 concentration from indoor sensors.

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

 

Benefits

• wireless transmission of measured values and alarm status
• two battery slots for longer battery life
• external power input
• remote device setup possible from COMET Cloud (maximum 1x per day)
• protection class IP 20
• availability of the Sigfox network at a specific location

Before buying a device, check the availability of the Sigfox network. COMET devices on the Sigfox network can be used anywhere in the RCZ1 area. Read more about Sigfox Radio Zones (RC).
