Pyroelectric infrared language alarm isuse pyroelectricity infrared sensor as the probe todetect human body's special wavelength infrared signal. Non-contact detection distance, that is the body close to the protected areas' vision, alarm devicewill send outwarninglanguage. Sensor'sspectral rangeis 1 ~ 10μm, center is 6 μm, all All are in infrared bands, is decided by the optical properties of silicon window which packed in TO－5 metal shell.
