Many Devices Will Now Know If People Are Present - Even In Total Darkness
Check out this new technology that was developed originally for space and will be used in high-volume on earth. It's a sensor array that looks at heat and its 80x32 pixels are able to distinguish humans - and their movements.
Sure there are existing high-resolution (expensive) sensors that can see a person, and there are low-resolution (cheap) sensors that can't distinguish a person from a cat and just detect movement. What's new and different here is the underlying technology that enables it to see people at such a low low cost and in such a small size that it will lead it to be used ubiquitously in security cameras, HVAC systems, smart buildings, people counters, and who knows what other kinds of devices and appliances that will now be able to know if a human is present - or to even watch how they move (like Mission Impossible) to activate certain functions - even in total darkness.
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. MelDIR package
It's small at 19.5 x 9.5 x 13.5 mm and includes the sensor array plus an ASIC, all encapsulated in a vacuum-sealed package. It has a thermal resolution of 0.1 degrees Celsius which is 5 times better than the cheap thermopile sensors used now.
It is semiconductor technology that has been under development
at Mitsubishi Electric for 20 years!
