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
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
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).
