H0AR9x is sensor hub module with STM32F0 MCU and a variety of sensors:

  • Weather: TI HDC1080DMBT digital temperature and relative humidity sensor.
  • Light: Broadcom (Avago) APDS-9950 proximity, ambient light and RGB color sensor.
  • Sound: Knowles Acoustics SPM1423HM4H-B  MEMS microphone.
  • Motion: Panasonic EKMC1601111 proximity infrared motion detector (PIR).

Use this module as an indoors weather station, room monitoring node or put on board aerial or ground robotics platform to gather surrounding data. Connect with other Hexabitz modules to log sensor measurements, stream data wirelessly or control external devices based on sensor readings.
