Q
Does the ambient temperature affect
detection sensitivity?
Does detection take place when the ambient temperature
is higher than the human body? How about when the
ambient temperature is the same as the human body?
Does sunlight affect performance?
Yes.
Seasonal changes in the ambient temperature change the sensitivity of the
sensor. Detection becomes more difficult in the summer because there is
less difference between the ambient temperature and the surface of the
human body. In winter, the reverse is true.
Yes.
The sensor operates by detecting temperature changes caused by the
motion of a body of a different temperature than the ambient temperature.
Therefore, detection takes place when the ambient temperature is higher
than the human body. Detection is also possible even when the ambient
temperature is the same as the human body because not all parts of the
body are the same temperature and the differences are detected when the
body moves.
Yes.
When the sun suddenly shines or stops
shining on the sensor, temperature
changes occur. The sensor detects these
changes and may output a detection sig-
nal. Be sure to install the sensor in a
location not exposed to sunlight.
