Measure CO2, Temperature, And Humidity With One Compact Sensor

The WiNG-CO2 is a single wireless device that measures carbon dioxide, temperature, and humidity.  Tracking changes in air circulation allows you to monitor air handling equipment.  Quickly detect impeded airflow, stalled fans, leaks, blockages, or clogged filters. Use the WiNG-CO2 to measure air circulation and track building occupancy for the comfort and safety of your building’s occupants.

The versatility of the WiNG-CO2 makes it a perfect fit for a variety of applications including:

  • Tracking building air quality
  • Monitoring HVAC systems
  • Counting indoor human occupancy
  • Monitoring horticulture facilities and greenhouses

Reliable CO2 Monitoring

The CO2 module we use in the WiNG-CO2 sensor is self-calibrating, zero maintenance, and features:

  • Range of 0-2000 PPM
  • Accuracy up to 30 PPM
  • Selectable CO2 measurement interval
  • 15 year CO2 sensor life expectancy

Small Footprint, Big Battery Life

WiNG sensors are compact and unobtrusive, yet provide an industry leading battery life – WING-CO2 sensor batteries last up to five years under normal room temperatures and at the default two minute CO2 measurement interval.

WiNG sensors maintain this extended battery life while communicating readings to the WiNG-MGR web interface every 10-20 seconds.  We knew it was important to our customers that we didn’t sacrifice data responsiveness in order to extend our battery life.

Unprecedented Transmission Range

The WiNG system has an unprecedented transmission range. Ranges between sensors and manager: up to 100 feet through multiple walls, up to 270 feet through one wall, and up to 600 feet indoor, direct line of sight.

While this range is more than ample for most situations, sometimes applications require signals to be pushed through more complex physical or noisy RF environments. The WiNG-RXT range extender can be implemented in these situations to add up to 1,000 feet direct line of sight transmission distance to the application.

Designed With Your Facility’s Security In Mind

WiNG sensors communicate directly – and only – with a WiNG-MGR or WiNG-RXT.  Utilizing small, proprietary packets in the 900MHz or 868MHz frequency range.

WiNG sensors are not Wi-Fi based, do not have IP addresses, and do not utilize IP communications.  This means they cannot connect to your company’s Wi-Fi network and ensures that they cannot be used as unauthorized wireless access points.
