HC-SR501 PIR Motion Detector Sensor Module
Product Code: SNM005Category: Sensor Modules
HC-SR501 PIR Motion Detector Sensor Module
INSTRUCTION :
·
Sensing module for about a minute
after power initialization time, during the interval to the output module 0-3
times a minute in standby mode.
·
Should avoid direct lighting such as
interference sources close the surface of the lens module so as to avoid the
introduction of interference signal generator malfunction; use of the
environment to avoid the flow of the wind, the wind sensor will also cause
interference.<50uA
·
Sensor module using a dual probe, the
probe's window is rectangular, dual (A per B million) in the direction of the
ends of long, when the body passed from left to right or right to left when the
reach the dual IR time, distance difference, the greater the difference, more
sensitive sensors, when the body from the front to the probe or from top to
bottom or from bottom to top direction passing, dual IR not detected changes in
the distance, no difference value, the sensor insensitive or does not work; so
the sensors should be installed dual direction of the probe with human
activities as much as possible parallel to the direction of maximum to ensure
that the body has been passed by the dual sensor probe. To increase the sensing
range of angles, the module using a circular lens, the probe also makes sense
on all four sides, but still higher than the upper and lower left and right
direction of sensing range, sensitivity and strong, still as far as possible by
the above installation requirements.VCC, trig (control side), echo (receiving
end), GND.
SPECIFICATION :
·
Operating voltage range: DC 4.5-20V
·
Quiescent Current: <50uA
·
Level output: High 3.3 V /Low 0V
·
Trigger: L can not be repeated
trigger/H can be repeated trigger(Default repeated trigger)
·
Delay time: 5-200S(adjustable) the
range is (0.xx second to tens of second)
·
Block time: 1S(default)Can be made a
range(0.xx to tens of seconds
·
Board Dimensions: 32mm*24mm
·
Angle Sensor: <100 ° cone angle
·
Operation Temp: -15℃ ~
+70℃
·
Lens size sensor: Diameter:
23mm(Default)
FEATURE :
·
the automatic sensor: to enter the
sensor output range is high, people leave the sensor range of the automatic
delay off high, output low.
·
the photosensitive control (optional,
factory is not set) may set the photosensitive control during the day or light
intensity without induction.
·
the temperature compensation
(optional, factory is not set): In the summer when the ambient temperature
rises to 30 ~ 32℃, slightly shorter detection range, temperature
compensation can be used as a performance compensation.
·
two trigger mode: (can be selected by
jumpers) a, can not repeat the trigger: the sensor output high, the delay time
is over, the output will automatically become low from high; b, repeatable
trigger: the sensor output high after the delay period, if the human body in
its sensing range activities, its output will remain high until after the delay
will be left high to low (sensor module review Measured activities of each body
will be automatically extended after a delay time, and the final event of the
delay time Starting point of time).
·
with induction blocking time (the
default setting: 2.5S block time): sensor module, after each sensor output
(high change Into a low level),you can set up a blockade followed by time
period, in this time period the sensor does not accept any sensor signal. This
feature can have a "sensor output time" and "blocking time"
the interval between the work produced can be applied to detect the interval
Products; also inhibit this function during load switching for a variety of
interference. (This time can be set at zero seconds - Tens of seconds).
·
the working voltage range: the
default voltage DC4.5V-20V.
·
micro-power consumption: static
current "50 microamps, especially for battery-powered automatic control
products.
·
the output high level signals: types
of circuits can be easily and docking.
·
the working voltage range: the
default voltage DC4.5V-20V.
APPLICATIONS :
·
Security Products
·
the human body sensors toys <50uA
·
the human body sensor lighting
·
industrial automation and control,
etc.
·
It can automatically and quickly open
various types of incandescent, fluorescent lamps, buzzer, automatic doors,
electric fans,automatic washing machine and dryer Machines and other devices,is
a hightech products. Especially suitable for enterprises, hotels, shopping
malls, warehouses and family aisles, corridors and other sensitive Sense of
region, or for the security zone automatic lighting, lighting and alarm
systems.
