Senseair Aercast    EOL (End of Life)

Senseair Aercast is a 3-in-1 indoor air quality sensor with built-in CO2, temperature, and humidity sensors. Battery operation for about 2 years is achieved by adopting low current consumption Senseair Sunrise for the CO2 sensor. Each measurement data value can be displayed on the LCD or checked by using the smart device application.

Furthermore, the air quality obtained from the measurement data is presented with four colors (green, yellow, orange, and red). 


  • Equipped with CO2, temperature and humidity sensors
  • Battery operated
  • Display of measured air quality data on LED as well as color-coded presentation with four colors
  • Connection to smart devices via wireless communication
