Senseair Aercast

Battery-powered and IoT connected indoor air quality monitor with CO2, temperature & RH measurement.



  • CO2, temperature & RH
  • Battery-powered
  • IoT connected
  • IAQ indication

Aercast is an advanced and versatile 3-in-1 transmitter designed for installation in the air-conditioned zone. It accurately measures CO2 concentration, temperature, and humidity in ambient air without the need for additional compensation true read. The data transmits to a BMS system or standalone controller using industry standard output signals and communication protocols.

Aercast combines all the necessary elements for effective climate control in commercial office buildings, hospitals, hotels, schools, and other facilities. Using CO2-monitoring for demand control ventilation (DCV) allows a healthy, comfortable, and cost-effective environment for the occupants. It is flexible in design, with temperature control and combination of humidity control optional. Though suitable for use in many different energy-efficient ventilation strategies, Senseair welcomes any discussions for specific needs.

Complies with ASHRAE standard 189.1 (±50 ppm @ 1,000 ppm of measured CO2 value).
