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.
