Product Description Our latest! Sound and light control / relay switch for voice module, the entire network the only sound sensitivity / sensitivity intensity / adjustable delay 1-60 S overall performance of the whole, super stable! Note: baby board with red and green, we do not accept the choice, random delivery. Module usage: The ambient sound and light intensity are automatically detected, and when a sound exceeds the set limit, the relay is activated, and the time delay period is automatically turned on, and then turned off. Light control function can be turned on and also turned off. Control the appliance for a certain light intensity or light intensity or less open. Microphone picture and welding with photosensitive resistance are for demonstration purposes only, to avoid interference from the relay's shutdown microphone sound, the effective delivery of products with an extension cable. Module Features: 1. Voice / Sound and Light Control Optional: You can use only the voice, the sound and light control function can also be used at the same time. 2. The two sound amplifications, 100-5000 adjustable gain, (corresponding to about 10 to 90 decibels of sound), adjustable sound intensity threshold. 3. Light intensity threshold 10-10000LX adjustable sensitivity (more or less corresponding to full black for the sunny half-day shade of brightness) 4. Pull 1-60 S adjustable delay time (for non-precision delay, capacitor charging and discharge delay time, with sound triggering a relationship). 5. Reverse polarity protection, reverse power supply will not work, will not burn the module. 6. Wide input voltage 5-30 V, ultra-wide range. Module Parameters: Power supply voltage: 5-30 V (Turn off the power supply when 6V short-circuit cap, remember! Incorrect selection may burn the module) Sound intensity range: about 10-90 dB adjustable. Light intensity band threshold: about 10-10000Lx adjustable. Delay time: 1-60 S adjustable (non-delay, precision capacitor charging and discharge delay time, with sound trigger) Highest load current: 10A / 220V Module size: 50mm * 33mm * 18mm (L * W * H), with M3 screw mounting holes placed. Special Note: Recently buyers say the following questions 1: Instability Delay times, this module delay capacitive discharge delay, the delay length completely triggered by the sound of capacitor charging and discharge decision. Trigger looks good, delay the point president, the small point delay sound becomes lower, the test is very simple gas sensor blows on, the trigger delay is certainly much more than talking. 2: trigger stop, the sensor can perceive any sound, relay output, the relay will be the voice of Cake, will trigger the module solutions: (1) move the sensor away from the relay (carry the sensor 20 cm line, for more self-stretched); (2) reduce the sensitivity slightly, the sound can be filtered out from the relay. Operation and Wiring Instructions (Very Important! Always Read Carefully) Module shipments have been detected before, but due to different specific areas, adjustments need to be made for the track you want to use. The procedure is as follows: The module uses a multi-turn precision potentiometer, can be turned upwards about 30 weeks, be patient adjustable rotating head can hear a faint sound of Cake, this time would not have rotated. The basic idea is as follows: turn off the light control function, delay time to the minimum, adjust the sound intensity, and then adjust the delay, finally adjust the light intensity. Remember that the power to select the pin is not wrong! 1. Ensure the photoresistor has been wrapped with black tape (matte type open type, turn off the light control function before commissioning corresponding) 2. Power supply to the module: Confirm positive and negative (reverse will not burn, but will not work), if the supply voltage is 6V, be sure to turn off the short-circuit cap! Otherwise, the module will burn !!! 3. Clockwise button
