Input voltage: 24 V. Sound\nintensity threshold range: 20 dB ~ 90 dB. Light intensity threshold range:\n10Lx ~ 10000Lx. Delay time: 1s ~ 60s (inaccurate delay, delay in capacitor\ncharging and discharging related to the triggering tone) Maximum load current:\n10 A\/220 V. Use method and introduction: 1. Make sure the photo resistor is\nwrapped with black tape (the module is a light-free open type, which\ncorresponds to turning off the light control function before debugging). 2.\nPower the module: confirm the positive polarity (the reverse connection does\nnot burn through but does not work) 3. Adjust the delay knob clockwise to\nminimize delay and make it easier to adjust the sound intensity. 4. When\ndebugging in a quieter environment, the sensitivity threshold adjustment knob\nincreases counterclockwise sensitivity and reduces sensitivity clockwise. 5.\nFirst set clockwise so that the relay does not close (the LED goes out). Then\ntalk or clap your hands to see if the LED lights up (as it gradually turns to\nthe shortest value, it goes out immediately afterwards). Adjust the setting\ngradually until you need the desired sensitivity. 6. After the sound intensity\nis set correctly, gradually set the delay timer counterclockwise by talking or\nclapping to trigger the module until the desired delay time is reached.\nGradually expand to 1 minute. 7. If you want to use the light control function\n(only pull if there is no light), remove the black tape from the photo\nresistor and adjust the light intensity button. Turn clockwise to dim the\nlight and counterclockwise to make it stronger. Turn off the light control\nfunction and simply cover the photo resistor with opaque tape.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eIt is a relay switching module. It can automatically detect ambient noise and light intensity. When the sound exceeds a set threshold, the relay automatically pulls, delays for a certain period of time, and then turns off. The light control function can be activated or disabled. It can be used to control the device and turn on below a certain sound\/light intensity.\u003c\/li\u003e\n         \u003cli\u003eFeatures: 1\u0026gt;.Product built-in relay switch; 2\u0026gt;.It can adjust the acousto-optical control threshold; 3\u0026gt;.It can adjust the delay time; 4\u0026gt;.It can only use the voice control function, or it can be used at the same time; 5\u0026gt;.It has a reverse polarity protection function, the power supply does not work reverse and the module is not damaged; 6\u0026gt;. It supports a wide voltage .\u003c\/li\u003e\n         \u003cli\u003eIntroduction The module uses a multi-turn precision potentiometer, which can rotate for up to about 30 weeks, so please adjust it patiently. After turning to the head, a slight click is heard. Do not turn it at this time.\u003c\/li\u003e\n         \u003cli\u003eUse method: first turn off the light control function, set the delay to the minimum, adjust the sound intensity, then set the delay, and finally adjust the light intensity. Be careful not to select the wrong power supply pin.\u003c\/li\u003e\n         \u003cli\u003eNotes: 1. The higher the supply voltage, the stronger the module heats up. This is a normal phenomenon. For long-term operation, it is recommended that the voltage is below 24V. 2. The sensor cable is a wear part. It is recommended to use it with care or prepare spare parts. 3. This module has a certain technical content, should buy it with care.\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"MEROURII","offers":[{"title":"Default Title","offer_id":45743556624537,"sku":"de-B08BP9SFHR","price":176.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0491\/3148\/7385\/files\/de-B08BP9SFHR.jpg?v=1775750103","url":"https:\/\/soundstores.net\/products\/sound-sensor-relay-switch-module-12v-24v-microphone-light-sensor-controller-module-3s-60s-adjustable-relay-delay-switch-module","provider":"SoundStore Australia","version":"1.0","type":"link"}
