W3711 WiFi temperature and relative humidity sensor for COMET outdoor sensor

Description

The W3711 WiFi-enabled sensors are designed to measure temperature and relative humidity with a connected sensor (known as a probe) (optional).

Communication with the sensor is via a wireless WiFi network. The device allows you to send the measured values to the COMET Cloud (with a minimum interval of 5 minutes) or to the COMET database. The measured values are displayed on the LCD and on integrated web pages where they can be transmitted to third-party systems using the Modbus TCP protocol.

The device continuously evaluates the alarm limits of the measured values and can send an email if they are exceeded, or notify by audible or optical alarm. Two alarm limits are supported for each measurement channel.

Thanks to these unique features, the WiFi sensor can be used in a wide range of applications.

An A1879 adapter is available for purchase to power the W3711.
