By capturing the advanced temperature detection of people, objects, etc. which is difficult to obtain with passive infrared ray (PIR) sensors, Mitsubishi Electric's infrared sensors facilitate better identification of people and objects, and better discernment of people's movements. This sensor is ideal for crime prevention, surveillance systems, people-counting systems, air conditioning systems, and other control equipment utilizing temperature measurement, without the need for 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.
