65 mu A Human Body Infrared Sensor Module IR Pyroelectric Infrared
PIR Detector
Human body has a constant body temperature, general to 37 ° so will
issue a particular wavelength of about 10 um infrared, passive
infrared sensor is by detecting the human body and 10 um ir, so
other objects except the body does not trigger probe movement.Once
the intrusion detection area, the human body infrared radiation
through part of the lens focus, and pyroelectric receive, and the
output signal.Subsequent circuit after detection treatment generate
control signal, will receive a weak signal amplification, and then
drive relay, is made from the pyroelectric body induction switch.
product functional features
1. Automatic induction: when someone enter its sensing range input
high level, people leave the induction range automatically delay
closing high.The output low level.
2. Photosensitive control (optional) : the module's reserve
position, can install photosensitive control, strong or light
during the day without induction.Photosensitive control for
optional features, the factory not installed when the
photosensitive resistance.If you need, please buy separately.
3. Two trigger modes: ab cannot repeat, the BC repeatable.Can jump
line selection, the default for the BC.
A. not repeatable triggered: after induction output high level,
delay time is over, the output will be automatically from high
level to low level.
B. repeatable triggered: induction, the output level in the delay
period, if there is the human body in its induction within the
scope of activities, the output will always keep a high level, it
was not until after the people left time delay will be high level
to low level (induction module detects the human body after each
activity will be automatically postponed to a delay period, and in
the last activity time for delay time), the starting point of the.
4. Induction block time (default setting: 30 seconds) : after
induction module in every sensor output (high level to low level),
can be followed by setting a block of time, in this time period
sensors do not receive any sensor signal.This function can be
achieved (induction output and blocking time) the interval of the
work, can be applied to interval detection products;At the same
time, this function can effectively restrain the load switch
process of all kinds of interference.
5. Wide working voltage range: the default working voltage DC4.8 V
to 15 V.
6. Micro power consumption, static current 65 microamps, especially
suitable for a battery-powered electric products.
7. A signal output level: easy to dock with the various types of
circuit implementation.
