D203 PIR Sensor TO-5

The pyroelectric infrared sensor detects infrared radiation based on the properties of the pyroelectric material that its polarization changes with temperature. Double compensated sensing elements are applied to suppress interference caused by temperature change. As a result, the operating stability of the sensor is greatly improved. Security systems, burglar alarms, visitor confirmation, light switch control and smart toys etc. It can be used in many areas.
