["Product description\r\nOur latest! Sound and light control / relay switch of voice module, all the network the single sound sensitivity \r\n/ sensitivity intensity / adjustable delay 1-60 S total performance of the whole, super stable!\r\nNote: baby plate with red and green, we do not accept the choice, random delivery.\r\nThe module uses:\r\nThe ambient sound and the light intensity automatically detect when a sound exceeds the set limit, \r\nthe relay is energized and the for time delay period automatically, and then turn off. \r\nLight control function can be activated also be closed. The control apparatus for a certain intensity of light or \r\nintensity of light or less open.\r\n\r\nMicrophone for image and welding by photosensitive resistor only for demonstration purposes, in order to avoid the \r\ninterference of the relay off microphone sound, the effective delivery of products with an extension cable.\r\nModule Features:\r\n1. Voice / sound and light control Optional: You can only use the voice, sound and light control function can also be used at the same for time.\r\n2. The two sound amplification, 100-5000 adjustable amplification, (corresponding to about 10 to 90 decibels of sound), \r\nadjustable sound intensity threshold.\r\n3. The intensity of light threshold 10-10000LX adjustable sensitivity (more or less equivalent to full black \r\nfor the sunny half-day shadow of brightness range)\r\n4. Pull 1-60 S adjustable delay for time capacitor loading and unloading delay for time, \r\nwith sound triggering a relationship).\r\n5.Reverse polarity for protection, reverse of the power supply does not work, will not burn the module.\r\n6. Wide input voltage 5-30 V, ultra-wide scope.\r\nModule parameters:\r\nSupply voltage: 5-30 V ( Turn off the power supply when 6Vd shorting cap, remember! The wrong choice can burn the module)\r\nRange of sound intensity: about 10-90 dB adjustable.\r\nThe light intensity band threshold: approximately 10-10000Lx adjustable.\r\nDelay time: 1-60 S adjustable (non-delay, capacitor loading and unloading delay for time, with the trigger trigger sound)\r\nMaximum load current: 10A / 220V\r\nModule size: 50mm * 33mm * 18mm (L * for W * H), with a M3 screw mounting holes positioned.\r\nSpecial Note: Recently, buyers say the following questions 1: Instability Delay times, this module delay capacitive discharge delay, delay length fully triggered by the sound of capacitor loading and discharge decisions. Trigger looks great, delay the point president, the small point delay sound will be lower, the test is very simple gas sensor blowing on, the trigger delay is certainly much more than talk. 2: trigger stop, the sensor can perceive all sounds, the relay output, the relay will be the voice of the Kaka, will trigger module solutions: (1) the distance sensor from the relay (wear sensor 20 for cm line , For more self stretched); (2) the sensitivity down slightly, the sound can be filtered out of the relay.\r\nOperation and wiring instructions (very important! for Always read carefully)\r\nModule shipments have been detected before, but due to different specific areas, need to be adjusted for the track you want to use. Procedure is as follows:\r\nThe module using a multi-turn potentiometer, can be turned upwards about 30 weeks, please be patient adjustable for head can hear a slight sound of Kaka, this for time would not have rotated.\r\nThe basic idea is as follows: turn off the light control function, delay for time to the minimum, adjust the sound intensity, and then adjust the delay, finally adjust the light intensity. Remember that the power of selecting the pin is not wrong!\r\n1. Make sure that the photoresistor has been wrapped black tape (matt type open type, turn off the light control function before the commissioning the equivalent)\r\n2. The power supply to the module: Confirm positive and negative (reverse will not burn, but does not work), if the supply voltage 6V, be sure to turn off the shorting cap! Otherwise the module will burn !!!\r\n3. clockwise button to adjust the delay will be transferred to the lowest delay in order to facilitate adjustment of sound intensity.\r\n4. in the relatively quiet environment, debugging, the intensity of the threshold adjustment button sound sensitivity increase clockwise anti-clockwise sensitivity. First clockwise adjustment, so that the relay is not closed (LED off). Then speak or clap, observe the LED is lit (due to being transferred shorter then immediately off). Gradually adjust the sensitivity until you need it.\r\n5. After adjusting the appropriate acoustic intensity to gradually adjust the delay button to the left, shut down the talk module or clap your hands until the delay for time you need. Delay for up to one minute.\r\n6. If you want to use the light-control function (that is, only Mate has been sticking), the photoresistor upper black ribbon ripped, button adjust the light intensity. Clockwise as the dim light
