DC 5/12/24V Sound Sensor Light Control Relay Switch

 Our latest! Sound and light control / relay switch of voice module, all the network the single sound sensitivity 
/ sensitivity intensity / adjustable delay 1-60 S total performance of the whole, super stable!

The module uses:
The ambient sound and the light intensity automatically detect when a sound exceeds the set limit, 
the relay is energized and the time delay period automatically, and then turn off. 
Light control function can be activated also be closed. The control apparatus for a certain intensity of light or 
intensity of light or less open.

Microphone image and welding by photosensitive resistor only for demonstration purposes, in order to avoid the 
interference of the relay off microphone sound, the effective delivery of products with an extension cable.
Module Features:
1. Voice / sound and light control Optional: You can only use the voice, sound and light control function can also be used at the same time.
2. The two sound amplification, 100-5000 adjustable amplification, (corresponding to about 10 to 90 decibels of sound), 
adjustable sound intensity threshold.
3. The intensity of light threshold 10-10000LX adjustable sensitivity (more or less equivalent to full black 
for the sunny half-day shadow of brightness range)
4. Pull 1-60 S adjustable delay time (for non-precision delay, capacitor loading and unloading delay time, 
with sound triggering a relationship).
5.Reverse polarity protection, reverse of the power supply does not work, will not burn the module.
6. Wide input voltage 5-30 V, ultra-wide scope.
Module parameters:
Supply voltage: 5-30 V (<6 V> Turn off the power supply when 6Vd shorting cap, remember! The wrong choice can burn the module)
Range of sound intensity: about 10-90 dB adjustable.
The light intensity band threshold: approximately 10-10000Lx adjustable.
Delay time: 1-60 S adjustable (non-delay, precision capacitor loading and unloading delay time, with the trigger trigger sound)
Maximum load current: 10A / 220V
Module size: 50mm * 33mm * 18mm (L * W * H), with a M3 screw mounting holes positioned.
Special 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 cm line , For more self stretched); (2) the sensitivity down slightly, the sound can be filtered out of the relay.
Operation and wiring instructions (very important! Always read carefully)
Module 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:
The module using a multi-turn precision potentiometer, can be turned upwards about 30 weeks, please be patient adjustable swivel head can hear a slight sound of Kaka, 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 of selecting the pin is not wrong!
1. 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)
2. The power supply to the module: Confirm positive and negative (reverse will not burn, but does not work), if the supply voltage <6 V (l such as USB, 4 AA batteries), connect the shorting buffer ( Sent shorting cap insertion half, which is equivalent to without interpolation). If the voltage supply> 6V, be sure to turn off the shorting cap! Otherwise the module will burn !!!
3. clockwise button to adjust the delay will be transferred to the lowest delay in order to facilitate adjustment of sound intensity.
4. 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.
5. 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 time you need. Delay for up to one minute.
6. 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 (which is darker in order to pull) and the opposite direction of light becomes stronger. To turn off the light control function, use direct adhesive tape to cover the photoresistor.
