ACCEL is a motion sensor Unit. Integrated with ADXL 345 and ACC it is able to obtain 3-axis of Acceleration. ADXL 345 is a small, thin, ultra-low power consumption 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and it is accessible through I2C(addr:0x53) digital interface. In this Unit, we used I2C series interface.

What is an accelerometer?
An accelerometer is an electromechanical device that will measure acceleration forces. These forces may be static, like the constant force of gravity pulling at your feet, or they could be dynamic - caused by moving or vibrating the accelerometer.

What are accelerometers useful for?
By measuring the amount of static acceleration, due to gravity, you can find out the angle the device is tilted at with respect to the earth. By sensing the amount of dynamic acceleration - You can analyze the way the device is moving. At first, measuring tilt and acceleration doesn't seem all that exciting. However, engineers have come up with many ways to make really useful products with them.

  • An attempt to create a realtime "Artificial Horizon" on the M5.
    This is an example of using a triaxial accelerometer to determine whether a fish is hooked.
    The PID Control Learning Platform is based on an M5Stack Fire & BaseX with TOF and Accel Units, and some Lego NXT parts.

    good for children

    it's easy to make something. if you build lots of contents through the m5stack, you make better edu. and ecosystem.
