Sensors, sensors, acoustic waves with a microphone and the vibration sensors is a group of sensors that detect vibrations in the form of waves of different frequencies, zamieniających them into an electrical signal. In Botland, you will find suitable sensors for Your applications. Welcome to our store.

Sound sensors and vibration sensors

Sensors of acoustic waves with a microphone

The most well-known sound transducers microphones. The microphone is nothing more than elektroakustyczny Converter that converts a sound wave into an electrical signal. Usually detect waves in the audible frequency range and in the range from about 20 Hz to 20,000 Hz. In our offer you will find microphones with a diameter of 6 mm and a height of 2.7 mm! Their sensitivity is about 36-38 dB. If you need the sensor that you want to connect directly to the analog inputs of the microcontroller, we recommend the sensors of acoustic waves with a microphone in a module with the amplifier system, where the signal voltage of the microphone is amplified 100 times. This allows direct connection of a module pin assignment analog inputs fulfillment system like Arduino or Raspberry Pi. For more demanding there is a sound sensor detector with three extra outputs: Envelope (allows you to measure the amplitude of the sound signal via the analog inputs any of the microcontroller, the output Gate (allows the detection of exceeding the earlier threshold of the amplitude of the signal is a digital output.) and Audio output (analog signal, which can be connected, for example, headphones or speakers). For robotyków we also have sensors in the form of a module from the DFRobot Gravity.

Vibration sensors

The vibration sensor of the sensor waves on a much wider than the acoustic operating frequency range. In our store, there are sensors operating in the range from 0.001 Hz to 1000 MHz, which greatly increases its application possibilities. They are used, in particular, in security systems, car alarm systems, detection systems, motion of the body, as well as energy-saving switches. Available in Botland vibration sensors through the Grove connectors are compatible with most microcomputers / controllers, such as Arduino, Raspberry Pi, BeagleBone, and many others.
