Electronic Noise meter circuit can be build using op-amp and monolithic IC..measure sound intensity and noise level and display with warning beep..circuit diagram with descriptionLED project. To test the circuit, take moist cotton and place it on the sensor. A common piezo sensor is applied to detect vibrations/sounds because of pressure variations. I want to design a circuit that sensor whether you hand is over the sensor and if it is it stops and holds a light display and as soon as your hand is moved it carries on. Touch pad can be a small piece of Strip board. Been designed and fabricated using sound intensity sensor and display unit. The circuit applies readily available electronic parts and the circuit design is simple. Keep the touch pad in the place that is to be monitored. The objective of the project is to use an LED as a sensor and to use the same LED to output the information about the sensed light. Here condenser microphone is used as sensor of noise meter with operational amplifier (IC2) and corresponding passive components. Electronics Circuit Diagrams, Electronics Circuits Projects, Schematic for Circuits and Diagrams · Home · Contact Us · Disclaimer The entire circuit is divided into two section—the sensor and the power supply section. The illustration below The circuit operates by first forwardbiasing the LED for a fixed period. Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have created the world's first all-integrated sensor circuit based on nanowire arrays, combining light sensors and electronics . Green LED lights if there is sufficient moisture. In this period he has supported many electronics/electrical engineering students in their final year projects. Connect the adjacent tracks of the touch pad to points A and B using thin wire.
