COMET W4710 – WiFi Sensor for Temperature, Humidity, CO₂, and Barometric Pressure with Integrated Probe

COMET W4710 Integrated WiFi T+RH+CO₂+Pressure Sensor 

The COMET W4710 is a powerful 4‑in‑1 WiFi sensor for temperature, relative humidity, CO₂ concentration, and barometric pressure with an integrated probe – the ultimate solution for modern, wireless indoor air and environmental monitoring in offices, schools, server rooms, museums, greenhouses, production halls, or wherever an existing WiFi infrastructure is available. Simply place it, connect to the WiFi network – and the W4710 automatically transmits all measured values to the COMET Cloud (from 5‑minute intervals) or to your own system.

The maintenance‑free NDIR CO₂ sensor (0–5000 ppm, optional up to 10,000 ppm), combined with precise temperature (±0.4 °C), humidity (±1.8 % RH), and pressure measurement, provides comprehensive climate data including dew point calculation. If any threshold is exceeded, the sensor alerts via e‑mail, acoustic signal, or visually through the LCD display – with two user‑configurable alarm limits per measured parameter.

Values can be viewed via integrated 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/year), you get a complete monitoring solution without the need for your own server, including charts, exports, alerts, and remote access via app or web browser.

The robust housing, large LCD display, and simple setup via WPS or web interface make the W4710 the ideal all‑in‑one sensor for smart‑building applications, Industry 4.0 environments, and professional monitoring – made by COMET.

Setup – done in minutes

Connect the sensor, link it to WiFi (using WPS or App), activate COMET Cloud – done. The measured values are automatically transmitted to the cloud or your system.

Summary:

  • Sensors with WiFi interface measure temperature, relative humidity, CO₂ level, and air pressure via an integrated probe (included). 
  • Communication with the sensor is wireless via WiFi. 
  • The device enables transmission of measured values to the COMET Cloud (with a minimum interval of 5 minutes) or to the COMET database. 
  • Values can be displayed on integrated web pages and forwarded to third‑party systems via Modbus TCP, SNMP, JSON, and XML. 
  • Measured values are shown on the LCD display.
