Panasonic Releases World’s 1st SMT Thermopile Array Sensor

08 October 2012

Years of continuous research in infrared sensing technology led to the development of a state-of-the-art thermopile sensor that features 64 thermopile elements in an 8 x 8 grid format.

Panasonic Electric Works Europe AG, the European headquarters for Panasonic Corporation’s Industrial Devices business, announces the release of the first ever Surface Mount Technology (SMT) thermopile array sensor, the Grid-EYE. Years of continuous research in infrared sensing technology led to the development of a state-of-the-art thermopile sensor that features 64 thermopile elements in an 8 x 8 grid format.

Contrary to conventional thermal sensors that only measure temperature of a certain point-of-contact, Grid-EYE, based on Panasonic’s MEMS technology, can measure temperature of the entire specified area without any contact; in other words, it is a “contact-less thermopile array sensor”. 64 pixels yield accurate temperature measurement over a viewing angle of 60° provided by a silicon lens. Grid-EYE uses an I²C communication interface, enabling temperature measurements at speeds of 1 or 10 frames/sec. An interrupt function is also available.

Product features:

  • Dimensions: 11.6 x 4.3 x 8.0mm (L x H x W)
  • Operating voltage: 3.3V or 5.0V (depends on P/N)
  • Temperature range of measuring object: -20°C to 100°C (depends on P/N)
  • Field of view (FoV): 60°
  • Number of pixels: 64 (vertical 8 x horizontal 8)
  • External interface: I²C (fast mode)
  • Frame rate: 10 frames/s or 1 frame

Compared to single element thermopile sensors or pyroelectric sensors, Grid-EYE offers immense benefits.

Grid-EYE opens the door to a whole world of applications, ranging from energy savings in the lighting industry (commercial and public places as well as residential spaces) to household applications (air conditioners, microwave ovens, etc.); from security systems (automatic doors, elevators, ATMs, kiosks, etc) to the medical industry (patient detection and positioning), and many more.

Applications:

  • Occupancy detection
  • Position detection
  • Contact-less temperature measurement
  • Cooking stoves
  • Microwave ovens
  • Medical equipment
  • Measurement, control and regulation of:
  •     o Air conditioners
  •     o Heating systems
  • Building automation
  • Intelligent lighting control system
  • Thermal imaging
  • Industrial process management and control
