Product Description Our latest! Sound and light control/relay switch with voice module, all network uniform sound sensitivity/sensitivity intensity/adjustable delay 1-60S total performance of the whole, super stable! Note: Children's plate with red and green, we have no choice, random delivery. The module uses: Ambient sound and light intensity automatically detect when the sound exceeds the set limit, the relay is supplied with voltage, and the time delay period is automatically, then shut down. The light control function can also be activated when closed. A control device up to a certain light intensity or Light intensity or less open. Microphone image and welding with photosensitive resistor for demonstration purposes only, in order to avoid Relay microphone sound interference, effective delivery of products with extension cable. Module Features: 1. Voice control/sound and light optional: Only voice control function, sound and light can be used at the same time. 2. Two sound gain, adjustable 100-5000 gain, (equivalent to about 10 to 90 decibels of sound), Adjustable sound intensity threshold. 3. Light threshold intensity: 10-10000LX, adjustable sensitivity (more or less equivalent, full black, For solar semi-daylight shade, brightness range), 4. Pull 1-60S adjustable delay time (for imprecise delay, capacitor charge and discharge delay time, With compound trigger sound). 5. Reverse polarity protection, reverse power supply does not work, will not burn the module. 6. Wide input voltage 5-30V, ultra-wide range. Module parameters: Supply voltage: 5-30V (turn off the power when short circuit 6Vd, remember! Wrong choice can burn the module) Sound intensity range: about 10-90 dB adjustable. Luminous intensity threshold: about 10-10000Lx adjustable. Delay time: 1-60S adjustable (no delay, precise capacitor charge and discharge time, with trigger sound) Maximum load current: 10A/220V Module size: 50mm*33mm*18mm (L*W*H), with M3 screw mounting holes set. Special Note: Recently, buyers say the following questions 1: Volatility Delay Times, Module Capacitive Discharge Delay, Delay Length Fully Triggered by the Sound of Capacitor Charge and Discharge Decisions. The trigger looks great, it delays the president's point, the sound of the delay of the small point will be lower, the test is a very simple gas sensor, the trigger delay is certainly much more than talking. 2: trigger stop, the sensor can perceive all sounds, relay output, the relay will be KaKa's voice, it will trigger the module solutions: (1) relay distance sensor (20cm line consumption sensor, for more stretch); (2) Downward sensitivity, The sound can be filtered out from the relay. Operating and wiring manual (very important! Always read carefully) Module shipments have been detected before, but due to different specific areas, they need to be adjusted to the path you want to use. The procedure is as follows: The module using a high-precision multi-turn potentiometer, can be rotated upwards about 30 weeks, please be patient with the adjustable torsion head may hear a slight Kaka sound, this time it would not rotate. The basic idea is as follows: turn off the lighting control function, delay time to minimum, adjust the sound intensity, and then adjust the delay, finally adjust the light intensity. Remember, the power of choosing a pin is not bad! 1. Make sure the photoresistor has been wrapped with black tape (matte type open type, turn off the lighting control function before starting the equivalent) 2. Module power supply: confirm positive and negative (reverse will not burn but not work), if power supply voltage 6V, remember to turn off the short circuit plug! Otherwise, the module will burn! 3. The button to adjust the delay to the right will be moved to the lowest delay for easy adjustment of the sound intensity. 4. In a relatively quiet environment, debugging, the intensity of the threshold adjustment button sound sensitivity increases the sensitivity counterclockwise. First, adjust to the right so that the relay is not closed (LED off). Then speak or clap, observe if the LED is lit (due to a move shorter than immediately off). Gradually adjust the sensitivity until you need it. 5. After adjusting the appropriate acoustic intensity, to gradually adjust the delay button to the left, close the talk module or clap your hands until the delay time you need. Delay up to one minute. 6. If you want to use the light control function (that is, only the Mate sticks), the top black ribbon of the photoresistor ripping, the light intensity adjustment button. Clockwise when the weak light (which is darker to pull) and the opposite direction of the light becomes stronger. To turn off the lighting control function, use direct adhesive tape to coat the photoresistor. Input and Output Connection Diagram (此处放图 1A30115-01) Safety Precautions! 1.
