Increased awareness of the effects of air quality on individual health drives greater demand for accurate indoor/outdoor air quality measurements and ventilation control for appliances such as HVACs and kitchen hoods to improve the air quality or simply alert users about spoiled food in their refrigerators. This multi-purpose air quality sensor measures air quality outdoors, indoors and in refrigeration.

System Benefits​:

  • Evaluate indoor, outdoor or refrigerator air quality/sensors right away
  • Single solution with gas, humidity and light sensors
  • Dedicated MCU for AI-based powerful sensor data evaluation
  • Bluetooth® 5 communication avoids cables
  • Integrated Li-ion battery, ultra-low Iq DC/DC and Qi wireless charging
  • Available in three variants with an easy-to-use iOS and Android app:
    • Indoor air quality sensor
    • Outdoor air quality sensor
    • Refrigerator sensor




  • Quick evaluation platform for gas, humidity or light sensors
  • Bluetooth 5 communication, wireless charging, Li-ion 1-cell power path management
