Features:

1. automatic: when someone enters the sensing range is input high level, people leaving the induction range is automatically delayed closing high level. Output low level.

2. light control (optional): module to set aside a location, you can set the photo control, or strong light during the day without induction. Light control is an optional feature, factory photoresistance is not installed. If you want, please purchase the photoresistance installed.

3. two trigger modes: l not repeatable, h can be repeated. Jumper option defaults to h.

A. not repeatable trigger mode: after the sensor output high level, delay time is over, the output will automatically change from high to low level.

B. can repeat triggered way: that induction output high level Hou, in delay time paragraph within, if has human in its induction range within activities, its output will has been maintained high level, until people left Hou only delay will high level becomes low level (induction module detection to human of each times activities Hou will automatically extended a delay time paragraph, and to finally once activities of time for delay time of starting points).

4. induction blackout time (default setting: 0.2 sec): after each induction the induction module output (high level low level), you can immediately set a blackout time, during this time the sensor does not receive any sensor signal. This feature can be achieved (sensor output and blockade times) the interval between work, can be applied to interval detection products; at the same time this function can inhibit various disturbances load in the process of switching.

5. wide operating voltage range: default voltage DC5V to 20V

6. power consumption: quiescent current 65, particularly suitable for battery-powered appliances.

7. high level signal output: can be easily docked with the circuit.

Instructions for use: 1. the induction module powers on for about one minute after initialization, this module can output interval during 0-3 time, one minute after entering standby. 2. direct sunlight should be avoided as far as possible sources of interference, such as lighting close range module surface of the lens, so as not to introduce interference signals malfunction; using the environment as far as possible to avoid movement of the wind, the wind will cause interference to the sensor. 3. induction module used double Yuan probe, probe of window for rectangular, double Yuan (a, Yuan b Yuan) is located in more long direction of ends, dang human from left to right or from right to left walked Shi, infrared spectrum reaches double Yuan of time, and distance has poor value, poor value more large, induction more sensitive, dang human from positive to probe or from Shang to Xia or from Xia to above to walked Shi, double Yuan detection does not to infrared spectrum distance of changes, no poor value, therefore induction does not sensitive or does not work ; So when the sensor is installed should probe the dual directions and the directions of human activities up to parallel as far as possible, ensure human passes has dual induction by probes. In order to increase the sensing angle, this module uses the circle lenses, also make probes sensors on all sides, but in both directions up and down left and right side is still strong induction range, sensitivity, must still be installed as far as possible according to the above requirements.

Key points:

1. The high level time of the output of this product is adjustable, 2.5 seconds to 1 hour, the output time set at the factory.

It is 2.5 seconds, and you can change one chip resistor if you need to change it. Please read the resistance value corresponding to the typical delay time.

Refer to the relevant form below.

2. Blocking time, 2 seconds, not adjustable.

3. The factory is defined as repeatable trigger and cannot be changed.

4. The supply voltage of this module is 3.3V to 15V, and the limit voltage is 2.8V to 18V.

5. Module output timing is: output high level for 2 seconds after power-on, then go low, enter standby

status. If the delay time is changed, the time when the module outputs a high level after power-on will increase accordingly, which can be understood as

The startup time after entering the normal working state after the electric power will increase.

6. After installing the photosensitive element, it does not work during the day, work at night, does not contain photosensitive components, and works all day (There are no photodiodes on the module,please purchase separately if needed. Recommended: ordinary F3 photodiode)

It is considered that there is no photosensitive element installed.

7. This module is very sensitive, pay attention to the installation position, try to avoid the heat source radiation source (air outlet / direct sunlight)

8. The sensitivity of this module is adjustable, and you need to change a chip resistor. Please read the relevant table below for details.

grid.

9. When soldering with 220V ordinary soldering iron, it is necessary to unplug the power supply before welding. It is recommended to use

24V low voltage soldering iron, such as domestic white light 936.

10. If you follow the MCU and connect the lamp, please read the reference circuit diagram below.

Precautions:

About electricity

Recommended qualified power supply, ie output voltage, current and ripple factor are standard power supplies, otherwise it is a movie

There may be some exceptions to the stability of this product, such as: false, no newspaper, automatic cycle start, etc.

About false positives

1. To ensure the eligibility of the power supply, please refer to the first item.

2. Test to ensure that the product under test does not surround the moving object (sensing range)

3. The power supply initialization time is about 10s-30s. During this period, it is abnormal sensory, which may cause false positive artifacts.

4. During indoor testing, the sensor is sensitive to the surrounding environment and needs to remain stationary, and ensure that the next cycle step test is performed before the end of the first sensor signal. When testing outdoor, be sure to pay attention to the dynamic surrounding environment, such as birds. Pedestrians, passing vehicles, etc.

5. The signal current output by the module is very weak. It is easy to cause false alarms through the high power of the drive tube.

This product is a housing component and the metal is not easily penetrated, so this product should not be used in metal housings.
