Thermal Detectors for Movement Detection

Pyrodetectors from Excelitas use the pyroelectric effect to recognize temperature variations by detecting changes in the infrared radiation received. The devices shown below are suitable for for motion sensing and intrusion detection.

Excelitas was the first to introduce a family of detectors offering a digital signal output - the DigiPyro range is included in the table.
