ELECFREAKS has the most complete range of micro bit sensors on the market. We classify micro bit sensors into two types. One is the PlanetX micro bit sensors. This micro bit sensor series is our own developed sensor that can be spliced with Lego. Its unique design, with color-coded ports, is the only toddler-friendly sensor on the market.
The other is the Octopus micro bit sensors. This series of products is just like its name, like an octopus, with a more complex interface, more geeks, and more geek lovers. More suitable for programming learners.
What they all have in common is that they all have their own sound sensors that can be used to detect sound frequencies.
Most micro bit sensors are used to determine how well a computer is doing. Sound sensors are also used to detect sound frequencies. You can contact ELECFREAKS to purchase these micro bit sensors.
