Note: the existing two styles of PCB board, but the color and the line is a bit different, the style in the following shows that the delivery is random hair

iqiyi.com/w_19rt4l6zt9.html In the next, please drop down the page. parameter Package name:Sound and light control corridor lights delay control module; Operating voltage:220V Load:5-60W incandescent lamp.LED energy-saving lamps can not be used, please be aware of); PCB size:22*37mm Module function:The day does not light, the night sounds (propaganda clap) light, automatically shut down after a period of time delay, play to save electricity,Convenient control function. The kit circuit is simple, after repeated experimental results are good, the suite selection of high-quality new components, the failure rate is low, more than the quality of the market a lot of similarSwitch, homegrown, adequate supply, reliable quality, please rest assured to buy. Empty board shipments: Style two Resistance welding diagram: PCB board using A military grade FR-4 material, plate tolerance and stability of some parameters, A material is very strong, which is the interests ofRelative to the price of some other plate material. PCB board directly printed with the parameters of the components, in the case can not refer to the circuit diagram can be directly weldedThen, quite convenient. PCB batch is not the same, the color will be different, please understand. Characteristics of PCB plate: 1 pads to increase and spray tin, easy to weld, and many times the welding pad is not easy to fall off; 2 is not easy to occur from the bending (refers to the non – human cases of bending), poor plate will be produced with the changes in time and environmentRaw bending. 3 impedance is more stable and reliable; Spare parts delivery pictures: Bulk shipping list (bill of materials) Component nameNumber PCB board 1 1N4007Four MCR100-61 3MM red LED 1 9014 transistor1 25V 470UF capacitor1 25V 47UF capacitor1 5528 photosensitive diode1 100K resistance1 4.7K resistance 2 1M resistance 1 1K resistance 1 Microphone head 1 Delivery with socket Matters needing attention The 1 parts of the element type more, picking more trouble, people are not saints, we can not guarantee that each package of many elements, if there is less individualNo, the replacement, only refund the difference, we will also try many elements, hope Pro understanding. 2 individual components such as the resistance capacitor temporarily out of stock, the seller will send its symbolic circuit to the principle of near the value of the element instead of. 3 after welding, please help to debug, welding is not an error, then the general can be successful, if the welding failure, the shop is not responsible, we can not guaranteeCertificate you a weld on the 100% success, this is why the factory production line needs to repair the reasons for the work, the components are new, butWe cannot guarantee that new elements are all good, there is no way to do the various components were tested and then shipped, if so, the spare partsThan the finished expensive, so if we give the element according to the retail price of the store size adjustment, if it is a bad element, to the buyerBe in charge of. But we promise to do 100 percent after sales service, do our best to help you complete the production of friends. Therefore, when encountered in productionThe finished product did not achieve the results we have described, please do not rush to give us evaluation, remember to contact us after the sale service. Thank youCooperation, I wish you a happy shopping! Agree with the 3 money to shoot, there are different meanings please buy finished products, finished products we have a good test before delivery, thank you! When welding should pay attention to let the photosensitive resistance not to LED, if such a photosensitive resistance will detect the light, that is the day, so that the light has been no bright. Welding good finished product front and back: Style two Use wiring method 1: Use wiring method 2: Using method 2 wiring physical picture: Circuit principle: This circuit is designed to work with the voltage of 220V, which is used to control the power of incandescent lamp in 5-60W. In practical application, change the value of R4Can change the working voltage of the circuit, the voltage range of 5-250V should be controlled within the current can be controlled with tungsten wire under different voltage smallThe bulb (such as 220V R4, auto bulb) values of 150K, 22V 15K and other voltage scale. 220V alternating current through the bulb flow D2, D3, D4, D5, rectifier, R4 current limiting voltage, LED voltage regulator (and standby indicator), C1 filterAfter the output of about 1.8V of the DC power supply to the circuit. Because the LED uses the light emitting diode, on the one hand uses its forward voltage drop voltage regulation, at the same timeBy using the optical properties as the standby indicator. The control circuit is composed of R1, MIC, C2, R2, R3, Q1, and R5. stayAround the other light photosensitive resistor is approximately 10K-20k ohm, Q1 collector voltage is always in low potential, even ifAt this time, clap, the circuit also has no reaction. At night, the photosensitive resistor to 1M ohm, the lifting of the clamp effect of Q1, at this timeQ1 is in a state of amplification, if the silent ring, then the Q1 collector is still low potential, the thyristor due to no trigger voltage and turn off. When you clap your handsThe sound signal is received and converted into electrical signals by MIC, and the base of the audio signal is coupled to the base of the Q1 via the C2, and the positive half of the audio signal is added to the Q1 base, Q1By the state of saturation into saturation, equivalent to the thyristor control pole, the circuit has no reaction. The negative half of the audio signal is added to the Q1When the base is made of the base, the collector is increased to a high potential, and the output voltage of the thyristor is turned on, so that the main circuit is connected with a high potential.There is a current flow, equivalent to the switch closed, and in series in the circuit of the light bulb to work. At this time, the positive electrode of C2 is high potential, and the anode is low.Potential, the current through the R2 slowly to the C2 charge (actually C2 discharge), when the C2 at both ends of the voltage to achieve balance, Q1 re at a magnificationState, the thyristor turn off, the lights go out, changing the size of the C2 can change the time of the lamp’s out. This switch can be used with 60W following loadIn the home lighting and stair corridor and other places.
