The Renesas HVAC Environment Monitor Module is designed specifically for assessing the air quality in public buildings (PBAQ) to prioritize people's health and well-being. It measures the air and sound conditions and efficiently transmits the gathered information through multiple communication devices, including LTE, Wi-Fi, and Bluetooth® Low Energy.

System Benefits:

  • High-precision measurement of air conditions with high-performance sensors:
    • indoor air quality sensor,
    • humidity & temperature sensor,
    • air velocity sensor.
  • High-precision sound and noise measurement function.
  • Battery life can be maximized with the combination of low-power devices (sensors, MCU, communication, and power supply system).




  • Indoor air quality sensor
  • HVAC
  • Air conditioner
