Mitsubishi IR Sensors

Mitsubishi’s Electric Diode InfraRed sensor (MelDIR) is a thermal sensor for applications in the fields of security, surveillance, crime prevention, people counting, heating, ventilation and air conditioning (HVAC) and smart buildings.

MelDIR provides highly detailed thermal images for accurately distinguishing between humans and other heat sources and enables the identification of specific human behavior, such as walking, running or raising hands. It delivers high-pixel, high-thermal-resolution images using thermal diode infrared sensor technology that Mitsubishi Electric developed for the Advanced Land Observing Satellite-2 “DAICHI-2” (ALOS-2).

The first product available is the MIR8032B1-01. This compact, space-saving sensor has a package which is 80% smaller than that of existing sensors, and provides high-pixel, high-thermal-resolution images with a 10 times higher pixel resolution (80×32 pixels) and five times higher thermal resolution of 100mK, or 0.1 degree Celsius, compared to 16×16 pixel thermopile sensors currently sold in the market.
