Grove sound modules - microphones

The world's most popular sound sensor is something you know very well - the microphone. It can be a professional microphone used to record high-quality sound or a simple microphone that receives acoustic waves (e.g. in a laptop). Microphones are sensors that proportionally convert the energy of the mechanical vibrations of the magnetic diaphragm into electrical energy. The latter takes the form of a voltage that causes a current to flow in the coil winding. Of course, there are many types of microphones. The most common microphone designs used on stage and in recording studios are dynamic, ribbon and condenser microphones. In addition, there are a number of electronic modules that use electroacoustic, piezoelectric and electrostatic phenomena. Such technologies detect sound in a variety of industrial and medical devices, but also in programmable electronics. Most often, sensors of this type can detect sound waves, the frequencies of which fall outside the spectrum of the human audibility band. Good examples are ultrasonic sensors - used in the welding process of plastics, and infrasound sensors - used to inspect the structure of less dense materials. In this category you will find various types of Grove sound modules that have built-in more or less advanced microphones.

Buzzers - small, but necessary ‘beep’ engines

Buzzers are tiny speakers that are installed on many PCBs, e.g. computer motherboards. Surely you know the specific BIOS sound that is sometimes produced when a board is reset or an error occurs, right? A small buzzer is responsible for this sound! A buzzer is a small loudspeaker which, when voltage is added (e.g. as a result of some programmed action - in the case of the BIOS, it may be a motherboard error or data loading), produces a clear sound signal. This signal is a very simple beep. Most often, the design and operation of the buzzer is based on the vibration of the piezoelectric material between two electrodes. In order for the buzzer to generate sound, voltage must be applied to its electrodes - most often in the form of a PWM signal from the microcontroller output. Buzzers are used in all devices, not only computers. They can be installed in RTV and household appliances, in microwave ovens with sound signaling of the end of meal heating, alarm and warning devices, as well as in toys and robots. Equip yourself now with the highest quality Grove buzzers, which you can easily connect to your motherboard!

Highest quality Grove sound sensors

Grove sound sensors can have different levels of sensitivity depending on the device. Therefore, in this category you will find devices recommended for both professional and home use. The sound level sensors are designed to measure the ambient sound pressure level. They have a built-in electret microphone and an operational amplifier that filters the input signal from interference and a potentiometer for adjusting the gain of the output signal from the sensor (devices with the LM2904 chip). These components enable precise calibration, detection of sensitive acoustic bands. As we mentioned, the presented Grove sound sensors are fully compatible with Arduino and many other platforms. The configuration requires that the sensor output is connected to the input of the analog-to-digital converter in the Arduino. The sensor can also be connected to the input of a comparator or an operational amplifier, if we are working on devices detecting sounds with a threshold aplite.
