Infrared 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 advanced temperature detection of people objects, etc. which is hard to obtained by Passive Infrared Ray (PIR) sensors, 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, and other equipment for control temperature with temperature measurement, without using an expensive infrared cameras.
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
-
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
- 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
- *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°C). This cannot be used for medical diagnosis.
