Human Machine Interface (HMI) Solutions for Appliances

This reference design is designed to detect refrigeration odors. However, smart kitchen appliances have several features, such as color displays, touch control and sound feedback. Voice recognition is also an emerging feature for non-contact operation. Sensing functions such as humidity/temperature and gas sensors can also be added as additional features to these systems.

System Benefits

  • High-performance human machine interface (HMI), touch key with haptics, voice recognition, graphics and sound can be controlled by one MCU
  • Low power solution with high-efficiency power regulators, low power haptics controller and low power audio codec
  • Integrated sensing solution with high-performance gas sensor and temperature/humidity sensor

Target Applications

  • Refrigerators
  • Microwave ovens
  • Range hoods
  • Other kitchen and home appliances
