Murata – The IRA-S series of Infra-red sensors are ideal for use in smart lighting systems



The IRA-S series from Murata are leaded pyroelectric infra-red sensors which provide a good signal-to-noise ratio and reliable performance.

Used in security equipment as well as lighting control systems, the IRA series sensors help designers to prevent the risk of false proximity detection events. Used in smart lighting systems, the IRA-S sensors can enable a light to be switched on and off automatically depending on whether a person is present in the area to be illuminated.
