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. Funding Organisation: Spanish Ministry of Science and Innovation. Light-sensitive Alarm Project The circuit detects a sudden shadow falling on the light-sensor and sounds the bleeper when this happens. Been designed and fabricated using sound intensity sensor and display unit. Title: CERES-BACO (Electronic Circuits for Ultra-Low Power Wireless Sensor Networks). Here condenser microphone is used as sensor of noise meter with operational amplifier (IC2) and corresponding passive components. Tiny Dew Sensor Circuit Diagram. Participants: IUMA RFIC, USE and CEIT. The circuit will not respond to gradual changes in brightness to avoid false alarms. Hi, i'm working on a project at school and have a problem with using a sensor to trigger a transistor. Dew (condensed moisture) adversely affects the normal performance of sensitive electronic devices. The Moto X is expected to launch later this year and will be 'more contextually aware than other phones'; The Biostamp electronic tattoo is made of silicon and contains an electrical circuit, antennae and sensors that bend and move with the wearer's body; Proteus Digital Health's 'vitamin Dugan, who used to be head of the US Pentagon's Defence Advanced Research Projects Agency, explained that each signal emitted by the pill could be unique to each user.
