Infrared SensorsInfrared Sensors

Outline

This infrared sensor incorporates thermal-diode infrared sensor technologies originally developed by Mitsubishi Electric to realize higher pixel and high-temperature resolution performance. By capturing the detailed thermal images of people, objects, etc. and improving the performance of identifying people/objects and people's movements, this sensor is ideal for crime prevention, surveillance systems, people-counting systems, and air-conditioning systems.

Mitsubishi Electric also offers "User-support tools" including application proposal documentation, product evaluation kits, reference codes, reference designs and other items to support the development of customers' products.

Features

High pixel count and high temperature-resolution enable highly precise understanding of people/object movement

MelDIR Infrared sensor (80×32Pixels)
Thermal Diode
  • Mitsubishi Electric Original Pixel Structure

    • The supporting legs are ultrathin by an innovative semiconductor microfabrication technique
    • Mounting the thermal diode and high-performance amplifier on the same chip

Vacuum-sealing, Chip-scale Packaging Contributes to Compact Space-saving Size

Vacuum-sealing, Chip-scale technology
  • Vacuum-sealing, Chip-scale technology

    • Chip-scale packaging technology developed in-house
    • New packaging technology reduces product size to approx. 80% compared to conventional products*
  • *
    Compared to general 16x16 pixel thermopiles available in market.

Main Applications

Crime prevention / Patient monitor / Smart buildings / Counting people / Temperature sensitive equipment / Air conditioner / Other

Thermal image examples for each application

Thermal image examples for each application
  • *
    Image was obtained after heating the surface of the face to simulate the condition of having a fever. The color tone of the image was adjusted to define the difference in body temperature (i.e., difference between high body temperature and normal body temperature is approx. 2℃). This cannot be used for medical diagnosis.
