Query: Sensors based on micromechanical devices: mobile labs at the service of
  experimental science teaching   In this paper we discuss the use of sensors incorporated in mobile devices as
possible mobile laboratories at the service of teaching experimental sciences.
Mobile devices, smartphones, tablets, laptops, microbit cards, are a resource
for making measurements of the physical world, since they have a set of
built-in sensors that allow to measure position, linear speed, angular speed,
acceleration, pressure, sound, color, magnetic field, proximity or luminosity,
among others. Also, these devices have greatly improved the performance of
their video cameras, allowing to easily shoot at high speed and high
resolution. Given its portability it is possible to work in the laboratory
itself or in other areas such as a gym, a park or your own home, transcending
the traditional scope of the laboratory. In general, the measurements obtained
can be analyzed in the device itself or uploaded to the cloud to be analyzed la
