2pcs SR501 HC-SR501 HCSR501 Adjust IR Motion Sensor

Descripción del producto

• Easy operation-1 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.
• Easy operation-2 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.
• Easy operation-5 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. !!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)
• Easy operation-4 5, with induction blocking time (the default setting 2.5S block time) sensor module, after each sensor output (high change Into a low level),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 .
