Murata today announced the launch of the IRS-B series of dual and quad type surface mount pyro-electric infrared sensors. Believed to be not only the smallest PIR sensors in the world, but also the only surface mount devices available, the series are aimed at a broad range of energy saving applications in consumer appliances.

The series comprises three models, IRS-B210ST01, IRS-B340ST02 and IRS-B345ST03. Measuring just 4.7 x 4.7 x 2.4 mm, these extremely small devices offer high sensitivity and signal to noise ratio, high stability against temperature changes and a low power consumption. These cost effective sensors provide a cost effective method of waking up a consumer appliance, such as a television, photo frame or room lighting, from an energy saving standby mode to normal operation once human movement has been detected. The IRS-B345ST03 device also has the capability of detecting minor motion such as waving hand or head.
