Murata's pyroelectric infrared sensors are unique for their high signal-to-noise ratio and high performance. The wake up feature can be applied to many devices, etc. by utilizing the advantages provided by the high signal-to-noise ratio and excellent sensitivity to be able to detect people. The wake up feature can be applied not only to electronic devices but also to OA equipment, etc. with a long standby time during start up. Recent digital home appliances as well as MPF (printers) and other office equipment have a long standby time until they start up after the power is turned on. By switching the equipment to standby mode at the moment when a person is detected with a pyroelectric infrared sensor, the equipment can be activated when the power is turned on.
Digital signage inside stores and underground passageways. Because digital signage streams images on large screens, the electricity usage becomes significant. Therefore, it is necessary to limit power consumption by showing video when people approach the screen. In order to get people to notice the digital signage, it is necessary to start showing the video at the moment when people approach. While it is okay to continuously show the video in a location where people are constantly coming and going, if no one comes by for a while, a person at a certain distance away can be detected with the pyroelectric infrared sensor to start the equipment and begin showing the video.
