Infrared SensorsInfrared Sensors


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.
