Sound Activated Switch Circuit Electroschematics Home Sound Activated Switch Circuit Received by Email With this sound activated switch, control by sound may be very useful, not just on a robot but also for a bit of home automation, for example a sound activated light responding to a knock on the door or a hand clap. 3 Sound Activated Switch Circuits Explained | Homemade ... The post details 3 simple sound activated relay switch circuits which can used as a module for any system that might be assigned to trigger by detecting some kind of sound pressure level.Or simply applications such as a voice activated alarm security circuit. Make Your Switch Sound Activated All About Circuits Remember this little bit of magic? We're going to reproduce this device: learn how to make a sound activated switch which can be opened and closed with a double clap. The sound sensing device of the circuit is an electret microphone. The preamplifier circuitry connected to the microphone converts Simple Sound Activated Switch | Electronic Circuits Diagram Simple Sound Activated Switch Circuit diagram : Control by sound may be very useful, not just on a robot but also for a bit of home automation, for example a sound activated light responding to a knock on the door or a hand clap. Sound Activated Switch Circuit Schematic This is a sound activated switch circuit. It’s will turn on and turn off based on a loud sound such as clapping your hands. You can adjust the sensitivity (how loud of a sound will activate the circuit) from a pin drop to a Mack Truck Horn. Sound activated switch This little and useful circuit is sound activated.It drives 9 leds in this video.But with more powerful transistor you can drive a relay for driving much bigger loads. Sound Activated Switch Ways to Design Own Sound ... Simple Sound Operated Switch circuit In absence of any audio signal, pin 2 is at logic high and the output of comparator is at logic low, giving a low signal to the trigger pin of the 555 timer. The output of the timer is thus at logic high, keeping the relay at off condition. Sound Activated Switch ~ ELECTRONICS LAB Simple Sound Operated Switch circuit In absence of any audio signal, pin 2 is at logic high and the output of comparator is at logic low, giving a low signal to the trigger pin of the 555 timer. The output of the timer is thus at logic high, keeping the relay at off condition. Sound Activated Switch Relay Electronics Lab Clap switch Sound activated switch designed around op amp, flip flop and popular 555 IC. Switch avoids false triggering by using 2 clap sound. Clapping sound is received by a microphone, the microphone changes the sound wave to electrical wave which is further amplified by op amp. Audio Activated Relay Switch | Circuit Diagram This audio activated relay switch circuit can be used for variety of audio related tasks. For example it can be used to start a recorder only when an audio signal is received, switch on an amplifier on small audio signal etc. This little circuit can save a lot of power and also it is ideal for battery operated projects. Sensitive Sound Activated LED | Circuit Diagram The sensitivity of the circuit can be adjusted with 100K variable resistor. Working of the circuit The electret microphone detects the sound signals and change them in to electrical audio signals these signals are amplified by the transistor Q1 and further amplified by Q2. Circuit Project: Sound Activated Switch II | EEWeb munity With this sound activated switch, control by sound may be very useful, not just on a robot but also for a bit of home automation, for example a sound activated light responding to a knock on the door or a hand clap. The light will be automatically switched off after a few seconds. An alternative use Sound activated relay circuitlib Sound Activated Relay circuit (see electronic schematic) To capture the sounds, we use a microphone capsule and a small microphone preamplifier. The signal from the microphone is applied (through C1), to the non inverting input (pin 3) of the IC1 operational amplifier. Sound Activated Switch Electronic Circuit Diagram This is a sound activated switch circuit. It’s will turn on and turn off based on a loud sound such as clapping your hands. You can adjust the sensitivity (how loud of a sound will activate the circuit) from a pin drop to a Mack Truck Horn.
