Smart Electronics HC-SR312 Human body sensing infrared sensor PIR infrared module HC-SR312
Smart Electronics HC-SR312 Human body sensing infrared sensor PIR infrared module HC-SR312
9.Module lens: small lens
Functional features
a. Enhanced anti-interference, internal digital signal processing, direct high and low level output.
b. Repeatable trigger mode: that is, after the induction output high level, in the delay time period, if there is a human body
in its sensing range of activities, its output will remain high until the person leaves the delay time, before becoming low level
(that is: the induction module detects each activity of the human body will be automatically postponed after a delay time period,
and the time of the last activity as the starting point of the delay time).
