The pyroelectric infrared sensor detects infrared radiation on the basis of the characteristics that the polarization of pyroelectric material changes with temperature.Dual compensated sensing elements are applied to suppress the interference resulting from temperature variation with the EMI components. As a result, the operating stability of the sensor is greatly improved. Our products can be used world wide for many applications. Such as in security systems, burglar alarms, visitor
acknowledgement, light switch control and intellectualized toy, etc.
