Description
The sensor is equipped with a 3D MMA736L accelerometer from Freescale, it is used to measure acceleration in three axes. Built-in regulator allows you to power the module with any voltage in the range from 2.2 V to 5.5 V. The output data is sent to the central unit in the form of analog voltage. The pins are popular goldpin connectors for connecting the sensor via wires or via direct attachment to breadboard.

Attention! Before connecting, you must check out the documentation of the module. |
Dimensions
The outline of the chip fits in the rectangle of the size: 23 x 13 mm. Thickness of the whole does not exceed 2.5 mm. For mounting, there are two holes with an internal diameter of 2.2 mm.
Pins
Powering from 2.2 V to 16 V is connected to VIN pin.
X, Y, Z pins are the analog outputs of the respective axes of the accelerometer. The outputs are centered on the half of the value of the voltage of the pin 3V3. The positive acceleration causes an increase and a negative, voltage drop.
Pin of selecting the g-Select sensitivity, is internally pulled to ground, which determines the default range to:
- +/-1,5 G (800 mV/G) for MMA7361L
- +/-3G (440 mV/G) for MMA7341L.
Specifying the high state changes the range to:
- +/-6G (206 mV/G) for MMA7361L
- +/-11g (118 mV/G) for MMA7341L.
Pin-0g-Detect is in high status when all three axes detects 0G.
SelfTest Pin is internally pulled to ground.
Its connection is not required for proper operation of the module. Details are in the documentation.
The module can also be powered directly with the voltage from 2.2 V to 3.6 V indicated on pin 3V3.
