PIR sensors

20 July 2011 Opto-Electronics

Murata 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 devices are aimed at a broad range of energy saving applications in consumer appliances.

The series comprises three models – the IRS-B210ST01, IRS-B340ST02 and IRS-B345ST03. Measuring just 4,7 x 4,7 x 2,4 mm, they offer high sensitivity and signal-to-noise ratio, high stability against temperature changes and low power consumption. The 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 also has the capability of detecting minor motion such as a waving hand or head.
