Sound sensor module Microphone Light sensor Control unit Relay switch module
1. Description:
It is a relay switch module. It can automatically detect ambient sound and light intensity. When the sound exceeds the set threshold, the relay automatically closes, delays for a certain time and then switches off. The light control function can be turned on or off. It can be used to control the device and switch on under a certain sound / light intensity.
2. Function:
1> .Built-in product relay switch
2>. It can set the acoustic-optical control threshold
3>. It can adjust the delay time
4>. It can only use the voice control function or it can be used at the same time
5>. It has a reconnection protection function, the power supply does not work in reverse and the module is not damaged
6>. It supports a wide voltage input
3. Description:
1>. Product Name: Relay switching module
2> .Input voltage: 24V
3>. Sound intensity threshold range: 20dB ~ 90dB
4>. Light intensity threshold range: 10Lx ~ 10000Lx
5>. Delay time: 1s ~ 60s (inaccurate delay, capacitor charging and discharging delay, related to shutter sound)
6> .Maximum load current: 10A / 220V
7> Working temperature: -25 ℃ ~ 85 ℃
8> Working humidity: 5% ~ 95% RH
9> .Size: 50 * 33.5 * 21.5mm
4. Use the method and introduction:
1>. The module uses a multi-turn precision potentiometer that can rotate up to approximately 30 turns, so adjust it patiently. You can hear a soft click when you turn to your head. Do not turn it at this time. It's the threshold of the end.
2>. First turn off the light control function, set the delay to minimum, adjust the volume, then adjust the delay, and finally adjust the light intensity. Make sure you do not select the wrong power pin.
1.1>. Make sure the photoresistor is wrapped in black tape (the module is an open type without lighting, which is equivalent to turning off the light control function before tuning).
1.2>. Module power supply: confirm positive polarity (reverse connection of the device does not burn but does not work)
1.3>. Adjust the delay control clockwise to minimize the delay and make it easier to adjust the volume.
1.4>. Tuning in a quieter environment, the sensitivity threshold knob increases the sensitivity counterclockwise and the sensitivity decreases clockwise.
1.5> .First set clockwise so that the relay does not close (LED goes out). Then talk or clap your hands to see if the LED is on (because it gradually changes to the shortest, then it goes out). Adjust gradually until you set the sensitivity threshold.
1.6>. After the sound volume is set correctly, gradually adjust the delay timer counterclockwise, speak or clap so that the module starts up to the time you need. Gradually extend to 1 minute.
1.7> .To use the light control function (adjust only when there is no light), remove the black tape from the photoresistor and adjust the light intensity knob. Turn clockwise to dim the light and turn it counterclockwise to increase the amount of light. turn off the light control function, simply cover the photoresistor with opaque tape.
