Application:

Ambient sound and light intensity automatically detect when a sound exceeds the set threshold, the relay is automatically energized and the delay period of time, and then disconnect. Light-control function can be enabled also be closed. The control apparatus for a certain sound intensity / light intensity following open.

Features:

1> Sound and light control Optional: You can only use Sound control, sound and light control can also be used simultaneously, but the light control cannot be used alone.

2> The two-stage amplification sound, adjustable magnification 100-5000 times, (corresponding to about 10 to 90 decibels sound), adjustable sound intensity threshold.

3> The light intensity threshold 10-10000LX adjustable sensitivity (roughly equivalent to the full black to sunny midday brightness varies the shade);

4> Pull 3-60S adjustable delay time (non-precision delay, delay capacitor charging and discharging, with sound trigger a relationship).

5> Reverse polarity protection, power supply reverse does not work, will not burn module.

Parameters:

Power Supply Voltage: 7V-24V

Sound Intensity Threshold Range: about 20-90dB adjustable

Light Intensity Threshold Range: about 10-10000Lx adjustable

Pull-in Delay Time: 3-60 Seconds adjustable (non-precision delay, delay capacitor charging and discharging, a relationship with sound trigger)

Max Load Current: 10A / 220V

Module Size: 50mm x 33mm x 18mm (L*W*H)

Operating and Wiring Instructions: (Very important! please read carefully!)

Module is a multi-turn precision potentiometer, can be rotated up to about 30 weeks, so please be patient adjustment, swivel head can hear a slight sound of Kaka, this time would not have rotated.

Basic adjustment ideas: Turn off the light control function first, then adjust the delay to minimum, then adjust the sound intensity, and then adjust the delay, finally adjust the light intensity.

1. Make sure the photo resistor is wrapped in black tape (module matt open type, turn off the light before commissioning the equivalent control function);

2. The power supply to the module: Make sure the positive and negative (reversed not burn, but does not work), if the supply voltage <6V (l such as USB, 4 AA batteries), short-circuit plug cap (shipped shorting cap insert half of which is equivalent to not inserted). If the supply voltage> 6V, remember to unplug the shorting cap! Otherwise it will burn module! ! !

3. knob clockwise to adjust the delay will be adjusted to the shortest delay, in order to facilitate adjustment of sound intensity.

4. In the relatively quiet environment, debugging, sound intensity threshold adjustment knob counterclockwise sensitivity enhancement clockwise sensitivity. First clockwise adjustment, so that the relay is not closed (LED goes out). Then speak or clapping, to observe whether the LED light (due to the delay adjusted to the shortest, so then it will immediately go out). Gradually adjust the sensitivity until you need.

5. After a suitable sound intensity adjustment, gradually adjust the delay knob counterclockwise, talk or clap trigger module until the delay time you need. Delayed for up to 1 minute.

6. If you want to use the light-control function (that is, only to pull matte), the upper photoresistor black tape torn off, adjust the light intensity knob. Clockwise light dimmed (that is darker in order to pull) and counterclockwise light becomes strong. To turn off the light control function, the direct use masking tape to cover the photoresistor.

Notice:

1> Delay time of instability, this module delay capacitive discharge delay, delay length entirely triggered by the sound of the capacitor charge and discharge decisions. Trigger loud, chairman delay point, the sound of small delay will be shorter point, the test is very simple sensor to blow into the air, trigger delay definitely better than talking a lot longer.

2> Stop trigger, the sensor can sense all sound, the output relay, the relay will be the sound of Kaka, will trigger module solutions: (1) away from the sensor relays (sensor wear 20cm line for longer self lengthened); (2) the sensitivity down a little, the sound of the relay can be filtered out.
