Product Description
This PD spoof uses the 2721 hardware PD chip, which cannot be upgraded, cannot change the voltage, and cannot be solved with compatibility problems.
Think carefully before buying
risk warning:
1. The hardware chip will randomly apply for voltage, for example, you need a 15V model. It may produce other voltages
2. Hardware chip, can not be upgraded, can not choose voltage
3. Does not support charging head information reading
4. Does not support other gears except for fixing a few voltages, such as PPS gear
5. You forced a 12V tablet computer with 15V, causing the computer to overheat and cause a fire.
6. Does not support PPS gear arbitrary voltage selection
7. Compatibility is generally not guaranteed to be compatible with most charging heads
PDC004/PDC003 uses a hardware PD identification chip. The identification logic of this identification chip is: tricking to trigger a fixed voltage. However, if the voltage that needs to be deceived is not available, the voltage will be applied to the next file.
For example: 15v product PDC004/PDC003, your PD power supply is only 12V, or 15v next file is 12v, then the scammer will apply to the next file 12v. PD spoofing is a strict communication format, there will be no spoofing of higher voltages, and no voltage will be boosted or stepped down. It does not have the ability to change the power, voltage, and current of the power supply.
Remarks
There are many products in this store, and the products are updated frequently. The products of different production batches may differ from the page introduction graphics. The products are subject to change without further notice.
All structures, appearances, colors, components, interfaces, packaging, etc., all subject to the actual product received by the customer

Product Description
Note that the "source" here does not refer to the power source. It refers to the source of the shock.
The features of passive buzzer are:
1 There is no oscillator inside the passive, so if you use a DC signal, you can't make it sound. Must use 2K~5K square wave to drive it
2 The frequency of the sound is controllable, and it can produce the effect of "multiple mifa Solaxi".
3 In some special cases, a control port can be reused with LED
The features of active buzzer are:
1 The active buzzer has an internal oscillation source, so it will beep as long as it is powered on
2 The program control is convenient. The single-chip microcomputer can make a sound with a high and low level, but the passive buzzer can't.
Each set weighs about 6g

Introduction to 1602 Character LCD
Main technical parameters of 1602LCD:
1. Display capacity: 16×2 characters
2. Chip working voltage: 4.5—5.5V
3. Working current: 2.0mA (5.0V)
4. The suitable working voltage of the module: 5.0V
5. Character size: 2.95×4.35(W×H)mm
1 VSS power ground 9 D2 data

2 VDD power supply positive 10 D3 data
3 VL liquid crystal display bias 11 D4 data
4 RS data/command selection 12 D5 data
5 R/W read/write selection 13 D6 data
6 E enable signal 14 D7 data
7 D0 data 15 BLA backlight positive
8 D1 data 16 BLK backlight negative
Pin 1: VSS is the ground power supply.
Pin 2: VDD is connected to a 5V positive power supply.
The third pin: VL is the contrast adjustment terminal of the liquid crystal display, the contrast is weak when connected to the positive power supply, and the contrast when grounded
High, when the contrast is too high, it will produce "ghosting". When in use, you can adjust the contrast through a 10K potentiometer.
Pin 4: RS is the register selection, the data register is selected when the level is high, and the instruction register is selected when the level is low.
Pin 5: R/W is the read and write signal line, read operation at high level, and write operation at low level. When RS
It can write instruction or display address when it is low level together with R/W, when RS is low level and R/W is high level
The busy signal can be read, and data can be written when RS is high and R/W is low.
Pin 6: The E terminal is the enable terminal. When the E terminal changes from high level to low level, the LCD module executes the command.
Pins 7 to 14: D0 to D7 are 8-bit bidirectional data lines.
Pin 15: The positive electrode of the backlight.
The 16th foot: the negative pole of the backlight source.

1. The photoresistor module is the most sensitive to ambient light, and is generally used to detect the brightness of the ambient light, trigger the single-chip microcomputer or relay module, etc.;
2. When the module's ambient light brightness does not reach the set threshold, the DO terminal outputs a high level; when the external ambient light brightness exceeds the set threshold, the DO terminal outputs a low level;
3. The DO output terminal can be directly connected with the single-chip microcomputer, and the high and low level can be detected by the single-chip microcomputer, thereby detecting the change of the ambient light brightness;
4. The DO output terminal can directly drive our relay module, which can form a light control switch.

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.

2. By adjusting the potentiometer, you can change the humidity detection threshold (ie, control the humidity value). If you need to control the ambient humidity to 60% , the module will adjust the corresponding ambient humidity to its green light, and the DO will output high power. When the humidity is lower than the set humidity value, the output is high and the green light is off;
3. The DO output terminal can be directly connected to the single-chip microcomputer, and the high and low level can be detected by the single-chip microcomputer, thereby detecting the humidity change of the environment;
4. The DO output terminal can directly drive the relay module of our store, which can form a humidity switch to control related equipment to work in a suitable environment
