Mitsubishi Electric to Launch 80x60 pixel Thermal Diode Infrared Sensor

Identifies heat-source types and human behavior in wide areas and with high precision.

New MelDIR thermal diode infrared sensor (80x60 pixels)

Mitsubishi Electric Corporation announced today that its Mitsubishi Electric Diode InfraRed (MelDIR) sensor lineup will introduce on July 1 a new thermal sensor featuring a wide field of view (FoV) and high 80x60 pixel resolution for applications including security, heating, ventilation and air conditioning (HVAC), people counting, smart buildings and thermal scanners. The new MelDIR sensor accurately distinguishes between humans and other heat sources and enables the identification of specific human behavior, such as walking, running or raising hands.

Product Features
1)Wide field of view and high-pixel resolution
Wide FoV (78°x53°) and high pixel (80x60) resolution support accurate processing of infrared data.
Compared to conventional 80x32 pixel MelDIR, detection area is 2-4 times larger and thermal resolution of 100mK, or 0.1°C, is similar.
Small pixel size of thermal diode infrared sensor achieves same package size as conventional 80x32 pixel MelDIR.

2)Superior images achieved with faster frame rate and optimized sensitivity correction
Compared to a conventional 80x32 pixel MelDIR, frame rate is double and sensitivity correction is optimized for surrounding area for superior thermal images.
Accurate identification of fast-moving heat sources supports crime prevention, people counting, animal detection, etc.

3)User-support tools shorten development time
Customers can use application samples, evaluation kit, reference codes and application-specific reference designs to support sample evaluations, product planning and product development.

Main Specifications



Background
Infrared sensors that measure temperatures by detecting the infrared radiation of objects are already used widely for security, HVAC, people counting, smart buildings and thermal scanners. The demand is growing, however, for sensors that offer high pixel and thermal resolution to distinguish between humans and other heat sources and to identify specific human behavior. To meet this growing demand, Mitsubishi Electric will soon release a new MelDIR featuring a wide FoV (78°x53°) and both high-pixel (80x60) and high-thermal (100mK) resolution.

Environmental Awareness
This product is compliant with the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS) directives 2011/65/EU and (EU)2015/863.
