SUPER SOUND SWITCH IN LAHORE

When you first connect the supply voltage to the sound activated switch circuit, the relay will be energised because of the effect of capacitor C2. Allow a few seconds for the relay to be switched off. You can increase or decrease the ‘on’ period by changing the value of C2. A higher value results in a longer ‘on’ period, and vice versa. Do not use a value greater than 47 μ F. The sound coming from outside is senses by microphone and converts it to corresponding electrical signal where sensitivity of sound is controlled by potentiometer Note: work only clapped. CLAPPED TURN ON LIGHT AND AGAIN TURN OFF. Input AC: 220v Output DC: 12V
