HC-SR501 Human Body Infrared IR Sensor Module Arduino Pyroelectric Infrared PIR Detector
Overview:
1, the automatic sensor: to enter the sensor output range is high,
people leave the sensor range of the automatic delay off high,
output low.
2,the photosensitive control (optional, factory is not set) may set
the photosensitive control during the day or light intensity
without induction.
3, 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.
4, two trigger mode: (can be selected by jumpers)
a, cannot 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).
5, 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).
6, the working voltage range: the default voltage DC4.5V-20V.
7, micro-power consumption: static current "50 microamps,
especially for battery-powered automatic control products.
8, the output high level signals: types of circuits can be easily
and docking.

Instructions:
1. 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.
2. 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.
3. 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
4. Dimensions and Adjustment:
Note: The potentiometer clockwise to adjust the distance, sensing range
increases (about 7 meters), on the contrary, sensing range
decreases (about 3 meters).Delay adjustment potentiometer clockwise
rotation, sensor delay longer (about 300S), the other hand,
induction by the short delay (about 5S).
5. Applications
a, Security Products
b, the human body sensors toys
c, the human body sensor lighting
d, 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 high-tech 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.
