Sound Sensor Module Microphone Light Sensor Controller Relay Delay Switch Module

1.Descriptions: It is a relay switch module.It can automatically detect the ambient sound and light intensity.When the sound exceeds a set threshold,the relay automatically pulls in,delays for a period of time,and then turns off.The light control function can be enabled or disabled.It can be used to control the device and turn on below a certain sound/light intensity. 2.Feature: 1>.Product built-in relay switch 2>.It can adjust the acousto-optic control threshold 3>.It can adjust the delay time 4>.It can use only the voice control function,or it can be used simultaneously 5>.It has a reverse connection protection function,the power supply does not work in reverse,and the module will not be damaged 6>.It supports wide voltage input 3.Descriptions: 1>.Product Name:Relay Switch Module 2>.Input Voltage:24V 3>.Sound Intensity Threshold Range:20dB~90dB 4>.Light Intensity Threshold Range:10Lx~10000Lx 5>.Delay Time:1s~60s(non-precise delay,capacitor charge and discharge delay,related to the trigger sound) 6>.Maximum Load Current:10A/220V 7>.Work Temperature:-25℃~85℃ 8>.Work Humidity:5%~95%RH 9>.Size:50*33.5*21.5mm 4.Use Method and Introduction: 1>.The module uses a multi-turn precision potentiometer,which can rotate up to about 30 weeks,so please adjust patiently.You can hear a slight clicking sound after turning to the head.Do not rotate it at this time. 2>.Turn off the light control function first,adjust the delay to the minimum,adjust the sound intensity,then adjust the delay,and finally adjust the light intensity.Be sure not to select the wrong power supply pin. 1.1>.Make sure the photoresistor is wrapped by black tape (the module is a light-free open type,which is equivalent to turning off the light control function before
