Pyroelectric infrared sensor IRA series

Pyroelectric infrared sensors use the pyroelectric effect of pyroelectric ceramics, a type of piezo-electric ceramics, as a principle of infrared detection. 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.
