W3811P IoT wireless thermometer and hygrometer with external sensor, Sigfox COMET

Description

The W3811P wireless thermometer and hygrometer measures temperature and humidity via an external wired sensor. The simple and compact sensor can be easily installed on site where measurements are taken. It is also suitable for measurements in areas with potentially poor Sigfox reception. The cable length should not exceed 30 metres. With appropriate protection (e.g.: F0000 and F5300) sensor can be used in more demanding conditions.

The measured values are sent at a configurable time interval (10 min … 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. If you exceed these limits, the device will warn you by sending you a message. 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).

The W3811 also falls into this category, but does not have as long a battery life.
