I would like to detect small animals like
mice. What is the smallest object that can
be detected?
Will objects behind transparent panes
such as glass or acrylic be detected?
The minimum detection size is that of one multi-lens (a circle several mil-
limetres in diameter) when the object is in immediate proximity to the MP
Motion Sensor.
Detection takes place when the object blocks part of the detection area and
a temperature difference occurs. As the distance from the sensor increases,
the detection area grows, and a larger object is necessary to create the
temperature difference needed for detection.
The minimum detection size depends on the distance from the object to the
sensor and the magnitude of the temperature difference. Use the sizes indi-
cated in the following x-y cross-section diagram as a reference.
No.
The sensor can only detect wavelengths
that are 5 µm or longer.
Common materials such as glass can only
transmit near infrared wavelengths up to 2
µm, thus a person moving behind a glass
window will not be detected.
