HC-SR501 Human Body Infrared Sensor Module IR Pyroelectric Infrared PIR Detector
Introductions:
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.
