Motion sensor module (DIY)

Regular price $19.00 Sale

The vector sensor module features a gravity sensing gyroscope, magnetic field detection, and pressure sensing. Compatible with the DIY series.

The Microduino Motion(Microduino-10DOF) integrates four sensors including one sensor of 3-axis gyroscope and 3-axis accelerometer(MPU6050), one magnetic field strength sensor(HMC5883L) and a digital barometer sensor(BMP180). Adopting I2C interface, it can be widely used in automation control, such as aero modeling and self-balancing car.

Features

  • Adopt three I2C-communicating sensors, saving IO interfaces.
  • Small, stackable, and economic.
  • Open hardware circuit design and Arduino compatible programming development environment.
  • With a uniform Microduino interface standard and rich peripheral modules, it can easily connect with other Microduino modules and sensors.
  • 2.54mm (0.1 inch) pin pitch, compatible to bread boards and pegboards.

Specification

Magnetic field intensity sensor: HMC5883L

  • HMC5883L contains the most advanced high-resolution HMC118X series magnetic-resistive sensor;
  • Integrated circuit with Honeywell patents includes an amplifier, automatic degaussing actuator, offset calibration and a 12-bit AD converter which can control the accuracy of the compass to the range of 1 ° ~ 2 °;
