The range of detectors and sounders elektroakustycznych system of Grove modules from Seeed Studio, Arduino-compatible and a Raspberry Pi. Sensors allow you to build any applications that use audio signals to control (for example, switches acoustic), as well as the enrichment projects in the function of emission of a sound signal is triggered as a result of a specific event, for example, low battery level. In the proposal we have also modules of LEDs, which can operate with sensors and sound signalling devices.

Microphones are the most popular sensors
Microphones are sensors working on the principle of proportional energy conversion of mechanical vibrations of the membrane magnetic into electrical energy as the voltage that causes current flow in the winding of the coil. The most common MICS used on estradach and in recording studios microphones are dynamic, ribbon and condenser. For popular microphones also apply to sensors operating based on piezoelectric and electrostatic phenomena that enable the detection of sound in various applications, industrial, medical, robotics, as well as in identifying and tracing objects, for example, by echolokacji. The design of these sensors allows the detection of sound waves whose frequencies are outside the spectrum range of hearing for humans. For example, ultrasonic sensors are used in the welding process of plastics, as an example: ultrasonic sensors are used in the audit process structure of materials with a low density of most metals, e.g., wood, concrete, or cement. On the measurements taken by such sensors does not affect the exposure of the environment, as this may take place when measuring the ambient light sensors and recognition of colors.
Buzzery - one of the smallest speaker systems with a wide field of application
Buzzer is a small speaker that is influenced by the voltage on its findings, produces a clear signal. Most often, the design and operation of a buzzer, based on the shaking of piezoelectric material between two electrodes. To buzzer made a sound, its electrodes must submit an AC voltage, at the time, for example, in the form of a PWM signal output from the microcontroller. Buzzery find use in all applications that require a simple acoustic signal, such as, for example, a microwave oven with a buzzer to the heating of food, the device alarm and warning, and electronic toys. Buzzery they are used in the desktop computers of the PC class and make themselves known, in particular, in the course of warning the user about the enabling key assets. Due to its small size and low power consumption, also find application in gift playing cards.
High quality sound sensor Grove
Sensors of volume level is intended for the measurement of sound pressure level of the environment. Built-in electret microphone and the amplifier, the operating system, respectively, the filtering of the input signal from noise (bandwidth throttle depends individually from the model) and the potentiometer gain control of the output signal of the sensor (for the model on the basis of the layout of the LM2904), provide accurate calibration and use of these sensors in sensor applications for the detection of sound and measurement of its parameters. Sensors Arduino-compatible - their output is an analog signal voltage. The sensor output should be connected to the input of the Converter the analog to digital Arduino, and applications all pure hardware whose purpose is the detection of sound amplitude threshold, the sensor should be connected to one of the inputs of the comparator or amplifier is operating system, operating mode dyksryminatora window.
