Description
Working principle: This module is a delay module triggered by an external signal.
Specifically: 1)--to->2)--to->3)--to->4).

1) Supply power to the module (12v or 5V), and the relay will be closed immediately (at this time, the status of the module output terminal is: normally open and public conduction, normally closed and public disconnection)

2) The relay is disconnected after a delay of 0-25 seconds (the output status of the module at this time is: normally open and public disconnection, normally closed and public conduction)

3) Keep disconnecting until it is triggered by an external trigger signal, and the relay is closed again

4) After a successful trigger, the relay will be disconnected after a delay of 0-25 seconds. Note: If the trigger signal is always on, the module will be closed until the trigger signal disappears, and the module will start to delay timing. The delay is 0-25 seconds. open. (At this time, the relay returns to the state before triggering normally open and public disconnection, normally closed and public conduction).



In addition: (The trigger signal of this module can be provided by a separate power supply system and the power supply of the module may not be a power supply system. At the same time, the trigger level can be a high-level pulse or a low-level pulse, which has strong versatility.)

Module features:

1. Length*Width=52mm*16mm

2. The working voltage of the module is 12V

3. The module can be controlled: 10A 250VAC (AC), 10A 30VDC (DC) or less load.
4. The time can be adjusted by the potentiometer. The default is 0-25 seconds. It takes longer. You can replace a larger capacitor or potentiometer by yourself. You can also contact customer service before shipping. We will change it for you and ship it.
5. Delay time formula: T=1.1RC. For example: capacitance 47uf resistance 500K T=1.1*500000*0.000047=25.85 seconds.
6. The power supply of the module is equipped with a diode to prevent reverse connection of the power supply, so friends can rest assured to connect.
7. The signal end of the module is designed with optocoupler isolation, which has strong anti-interference ability, can adapt to the application of high and low level control signals, and is suitable for industrial control.
8. The module can be triggered repeatedly (for example, if you set a delay of 10S, if a trigger action occurs again within a 10S delay of a trigger, the 10S delay will be repeated when the action occurs again, that is, it will be triggered once after the ZUI within the undelayed period. Whichever is higher, delay 10S later, until the delay time reaches to complete the whole process of one trigger delay. After the delay is over, trigger again and delay again

9. No power consumption in standby (Almost power consumption in standby, zero current, greatly extending the life of the car battery. Green product)

Product application: It can be used for robots, car light delay, intelligent product development, automation equipment, PLC development, smart home, anti-theft alarm delay, electronic development, etc.

Precaution:
About electricity
Recommend a qualified power supply, that is, the output voltage, current, and ripple coefficient are all standard power supplies, otherwise it is a film
There may be some abnormalities in the stability of this product, such as: false, no report, automatic cycle start, etc.
About false positives
1. To ensure that the power supply is qualified, please refer to the first item.
2. Test to ensure that the product under test does not surround a moving object (sensing range)
3. The power initialization time is about 10s-30s. During this period, it is paresthesia, which may cause false positive artifacts.
4. During indoor testing, the sensor is sensitive to the surrounding environment and needs to remain still to ensure that the next cycle step test is performed before the end of the first sensor signal. When testing outdoors, be sure to pay attention to the surrounding dynamic environment, such as birds. Pedestrians, passing vehicles, etc.
5. The signal current output by the module is very weak. By driving the high power of the tube, it is easy to cause false alarms.
This product is a shell component, and metal is not easy to penetrate, so this product is not suitable for metal shells.

Features
1.The circuit consists of a triode multivibrator driving two groups of LEDs to flash alternately. When the LED gyro is rotated, the vibration switch is turned on and the circuit works. Due to the phenomenon of visual retention, the pattern is left.
2.The working principle of the circuit: when the battery is installed, the vibration switch S1 is turned off. When the gyro is rotated, due to the centrifugal effect, the vibration switch S1 is turned on and the circuit works.
3.The working principle of the multivibrator is that when the power is turned on, the transistors Q1 and Q2 should be turned on first. Due to the difference of components, only one is turned on first, and then the two transistors in the circuit are turned on and off in turn, and the cycle Glow, so there will be multiple dashed patterns.
4.It can not only develop skills for welding learning, but also complete a funning LED flashing light toy to bring fun to life.
5.Required tools: electric iron: 30W, solder wire: 0.8mm, tweezers, oblique pliers, multimeter.

Working parameters:
Pyroelectric human body infrared sensor module, model: SR-602
Sensing distance: up to 5 meters; recommended 0-3.5M.
Output: high level, H=3.3V, L=0V
Power supply DC: 3.3V-15V
Quiescent current: 20uA
Features and uses:
This module has high sensitivity, fast response, small static power consumption, small size, easy to install, and is installed.
The lens, the pin header has been soldered, and the power supply is provided without debugging. Can be used for body sensor lights, alarms, security,
Access control on-demand imaging, automatic equipment for agriculture, forestry and mining.
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.
