Are you a Do-It-Your selfer? Hone your soldering techniques on Clap Sound Activated Switch Soldering Kit. Just clap your hands together and watch the Sound Activated Switch turn on the light emitting diode (LED). Clap more and watch the LED turn off. A one-shot, or monostable multivibrator, is a circuit that, once triggered, will switch its output logic level. The output will remain at this new logic level for a predetermined period of time, after which the output will switch back to its previous logic state. This is the core of the Sound Activated Switch. The sound of clap is received by a small microphone in the circuit. The Relay contact is connected to the powerline and hence turns on/off any electrical device connect at output socket.All Electronic Parts for the Clap Switch Circuit, 12V Relay, PCB Supplied.No Transformer Supplied, No Soldering Iron, No Solder Wire. This is Combo kit and also very useful project for Vibration Touch, Anti Theft Circuit, Burgler Alarm Cirucit, Earthquake and many more The piezoelectric sensor is connected to the door using an adhesive. The sensor and the security system project circuit are connected using a wire., Piezoelectric sensor is basically called as piezoelectric transducer as it generates an electrical signal based on the measured input quantities such as vibration, flex, touch, knock, shock. Thus, whenever the piezoelectric film is subjected to vibrations (back and forth movement of piezoelectric film) causes the generation of low AC signal with high voltage (up to +/- 90V). If the door is knocked, the vibrations caused due to the knock produces mechanical energy. This mechanical energy is fed to the piezoelectric vibration sensor.Power Source: BatteryMaterial: PlywoodWeight: 250: 1 Electronic Hobby Kitbrand: pkeModel Number: Clap_Vib2016Type: EducationalMinimum Age: 3ROHS Complaint: NoWidth: 5 cmHeight: 10 cmBattery Type: 9 VNo Of Batteries: 1Battery Size: 9 VOther Power Features: Battery
