Discover XENSIV™ Sensors

Infineon’s sensors give human-like senses for better contextual awareness

Image of Infineon Technologies Discover XENSIV™ SensorsInfineon XENSIV sensor solutions enable simple and effortless user interactions with all kinds of intelligent devices. Thanks to industry-leading technologies, Infineon's sensors are the perfect fit for various applications, including consumer markets. Three of these solutions are the XENSIV digital barometric pressure sensor, the XENSIV radar sensors, and the XENSIV MEMS microphones.

XENSIV digital barometric pressure sensor

Infineon's digital barometric pressure sensor family is the best choice for mobile and wearable devices due to its small form factor, high precision, and low power consumption. Infineon's Shield2Go boards offer a unique customer and evaluation experience as the boards are equipped with one DPS368 barometric pressure sensor and come with a ready-to-use Arduino library.

XENSIV MEMS microphones

The Infineon XENSIV MEMS microphones introduce a performance class that overcomes existing audio chain limitations with low self-noise (SNR), wide dynamic range, low distortions, and high acoustic overload point. The popularity of voice user interfaces and the usage of audio recording to share information and experiences are increasing dramatically. However, the performance of microphones often limits the potential of today's cutting-edge devices. The Infineon Audiohub Nano enables the evaluation of Infineon digital PDM XENSIV MEMS microphones.

Features
  • 69 dB(A) signal-to-noise ratio
  • Below 1% distortions at 128 dBSPL (AOP: 130 dBSPL)
  • Digital (PDM) interface with 6 μs group delay at 1 kHz
  • Tight sensitivity (-36 ±1 dB) and phase (±2°) tolerances
  • 28 Hz low-frequency roll-off
Benefits
  • High-fidelity and far-field audio recording
  • Matched, noise, and distortion-free audio signals for advanced audio signal processing
  • Ultra-low group delay for latency-critical applications
  • No analog components required
Applications
  • High-quality audio capturing:
    • Cameras, camcorders, conference systems
  • Active noise cancellation:
    • Headphones and earphones
  • Voice user interface:
    • Smart speakers, home automation, and IoT devices
  • Audio pattern detection:
    • Predictive maintenance, security, or safety

XENSIV radar sensors

Infineon's 24 GHz and 60 GHz radar sensors cover a wide range of consumer and IoT applications. In contrast to other motion detection technologies like PIR, radar technology offers significant advantages such as smaller system sizes, greater accuracy, and more precise measurement of detected objects.

Features
  • Direction, proximity, and speed detection
  • Hidden mounting capability
  • Maintains operation through harsh weather conditions (such as temperature, light, and rain)
  • Motion tracking
  • Sensing through non-conductive materials
  • Target positioning
  • Adaptable to different application requirements
  • Precise positioning of multiple targets in a 3D space
  • Object classification
Applications
  • Smart buildings and smart homes (IoT)
  • Service robotics (vacuum cleaners/lawnmowers)
  • Lighting control
  • Industrial robotics (manufacturing robotics)
  • Outdoor lighting
  • Air conditioners
  • Smart street lighting
  • Health (vital sensing)
  • UAV/multicopters
  • Wearables
  • Security
