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).
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 (80x60 pixels) and five times higher thermal resolution of 100mK, or 0.1 degree Celsius, compared to 16x16 pixel thermopile sensors currently sold in the market.
