COMET W3710 – WiFi Sensor, Temperature, Humidity with Integrated Probe

COMET W3710 WiFi Temperature and Humidity Sensor 

The COMET W3710 is a smart WiFi sensor for temperature and relative humidity with an integrated probe – the perfect solution for modern, wireless monitoring in buildings, warehouses, server rooms, museums, greenhouses, or anywhere existing WiFi infrastructure can be used. Simply place it, connect to the WLAN, and the W3710 automatically transmits the measurements to the COMET Cloud (at intervals from 5 minutes) or to your own system.

This maintenance-free sensor measures temperature (−20 to +60 °C) and humidity (0–95 % RH) with high precision and calculates the dew point. If threshold limits are exceeded, it alerts you by email, acoustic signal, or visually via the LCD display. Measurements can also be viewed through built-in web pages or forwarded to third-party systems via Modbus TCP, SNMP, JSON, or XML.

With the free COMET Cloud (3 months free, then 1 credit per year), you get a complete monitoring solution without your own server: charts, exports, alarms, and remote access via app or browser. Alternatively, you can integrate the sensor directly into your SCADA, BMS, or IoT platform.

The robust housing, large LCD display, and simple setup via WPS or web interface make the W3710 the ideal entry point into wireless sensing – made by COMET.
