Infrared Sensors

Murata pyroelectric infrared sensors feature minimal variation thanks to the application of unique pyroelectric ceramic technologies cultivated by Murata over many years, and a high signal-to-noise ratio results in highly sensitive human detection capabilities, with low malfunctions and false positives.

Because the IRA series uses passive components, the products consume a low amount of power. The IRA-S series maintains tried-and-true performance at low cost for products with excellent cost performance.
The lineup offers a selection of products perfectly suited to your applications and needs.

Because Murata pyroelectric infrared sensors are high performance and have a good signal-to-noise ratio, false positives are minimal, making them useful in security-related domains that require high precision and high reliability.
These sensors are frequently used in crime prevention systems by security companies, such as IP cameras and alarm systems, and in IoT smart home security.
Outside of the security domain, they are used in digital signage and vending machines, office equipment such as printers, conference displays, and PCs, and general household appliances such as air conditioners and air purifiers.
