In the radioactive process, manual switching poses great health hazards to the operator due to the side effects of exposure to the radioactive elements. This can cause financial strain on a company. In the industries like the petroleum or chemical industries, some production processes have been started or stopped due to accidental switching of machinery leading to injury or death. In industries, sound activated switch is used to control an alarm and time of danger when the security of any place in industries is needed, and also used to monitor intruders in any given environment by activating an alarm when the noise of the intruder gets to the microphone of the system.
SOUND CONTROL SWITCH HOW TO
This work also exposed me to application of transistor such as using transistor as a switch and also application of a relay such as relay is also used as a switch as well to control load.įinally, this work mostly exposed me to how to construct this system and also exposed me to know the applications of the system such as: homes, sound activated switch is as used to control a lamp in our rooms and environs. This study exposes me to the function of a microphone such as that microphone converts the pressure waves caused by sound into vibrations within a coil which transforms the vibrations into electric signals. A small sound activated switch circuit comprising a sound amplifier and a flip flop is presented here, which can be easily built and used to toggle any electrical gadget through hand claps. The article is meant exactly for the said purpose. Want to build a simple sound switch circuit that will toggle any load in response to your claps. The objective of this project is to design and construct a sound activating switch that can be used to control either a lamp or an alarm or any other load. It can be used to switch on/off any electrical appliances In homes, sound activated switch is as used to control a lamp in our rooms and environs. Sound activated switch has many applications both in homes and industries. The relay can be connected to an electric device to make the device turn on and off by the clap of hands or a similar sound. The amplified circuit is connected to a relay contact which acts as a mechanical switch. The flip-flop reverses the output and feeds another amplified circuit. The transistor feeds the amplified sound to a flip-flop circuit.
The electrical waves are magnified by a transistor. The sound is changed into electrical waves. The microphone detects sound, such as laughs, slamming doors, and claps of hands. The most important feature of the sound activated switch is its small microphone. Sound activated switch is an electrical device that allows appliances and products to be turned on and off from sound. The light will be automatically switched off when the sound is repeated. 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 relay can be connected to an electric device to make the device turn on and off by the clap of hands or a similar sound.Ĭhapter Four 4.0 Construction Procedure and TestingĬhapter Five 5.0 Conclusion and Recommendation This project is titled design and construction of sound activated switch.
