Abstract
Systems and techniques are provided for sensor device. A sensor device may include a housing, a lens inserted into a first opening of the housing, a metal mask covering a portion of the interior of the lens, a passive infrared (PIR) sensor underneath the lens and the metal mask, and a light pipe around the PIR sensor, the lens, and the metal mask. Part of the light pipe may be positioned above an activation mechanism for a button. An airflow gasket may be around the PIR sensor. A filter circuit board may be under the PIR sensor and connected to leads of the PIR sensor. A control circuit board may include the activation mechanism for the button. A backplate may include a slot for attachment to a snap of a magazine in the housing of the sensor device.
