Product Summary

The D204S is an Anti-Jamming Dual Element Pyroelectric Infrared Radial Sensor. 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 D204S is greatly improved. The D204S can be used world wide for many applications. Such as in security systems, burglar alarms, visitor acknowledgement, light switch control and intellectualized toy, etc.
