COMET W5714 – WiFi CO₂ Sensor with Integrated Probe

COMET W5714 WiFi CO₂ Sensor integrated 

The COMET W5714 is a professional WiFi CO₂ sensor with an integrated probe – the smart solution for modern, wireless indoor air quality monitoring in offices, schools, conference rooms, server rooms, production areas, warehouses, or anywhere an existing WiFi infrastructure can be used. Simply place it, connect to WiFi – and the W5714 automatically sends CO₂ readings to the COMET Cloud (from a 5‑minute interval) or to your own system.

The maintenance-free NDIR CO₂ sensor measures accurately from 0 to 5000 ppm and immediately indicates the current air quality via its three‑color LED indicator: Green = good (≤ 1000 ppm), Yellow = moderate (1001–1200 ppm), Red = poor (≥ 1201 ppm). When a limit value is exceeded, the sensor warns via email, acoustic signal, or visual indication on the LCD display – with two freely configurable alarm thresholds.

Readings can be displayed via integrated web pages or forwarded to third‑party systems using 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.

The robust housing, large LCD display, and easy setup via WPS or web interface make the W5714 the ideal CO₂ sensor for smart buildings, Industry 4.0, and professional air quality monitoring – made by COMET.
