The MMA7361L is a low power, low profile capacitive micromachined accelerometer featuring signal conditioning, a 1-pole low pass filter, temperature compensation, self test, 0g-Detect which detects linear freefall, and g-Select which allows for the selection between 2 different sensitivities.
0-g offset and sensitivity are factory set and require no external devices. The MMA7361L includes a Sleep Mode that makes it ideal for handheld battery powered electronics.
Another great feature of this product is the presence on-board of a 3.3V 50mA very low dropout linear voltage regulator, which allows this breakout board to accept a wide range of input voltages (2.7-6V).
Due to the low power consuption of the MMA7361L sensor a lot of power can be used for additional 3.3V components.
Note that for power saving sensitive applications it is possible to shut down the sensor, reducing the current to less then 3uA.
This board breaks out all the signals to a 0.1" (2,54mm) standard spacing header, in this way it is simple to use it with prototyping boards and also with breadboards.
Typical applications are:
- 3D gaming
- motion sensing
