   1pc HC-SR501 Adjust IR Pyroelectric Infrared PIR Motion Sensor  Detector Module






SKU: A876


Item Description


Electrical parameters:

Product Type: HC--SR501 Body Sensor Module
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: 2.5S(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 degrees
Lens size sensor: Diameter:23mm(Default)

There is not H/L jumper included in  this revision.

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, 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)
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.

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 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.
