MMA7361 Accelerometer Sensor Module 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 sensitivities. Zero-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. Specifications3mm x 5mm x 1.0mm LGA-14 Package Low Current Consumption: 400 μA Sleep Mode: 3 μA Low Voltage Operation: 2.2 V – 3.6 V High Sensitivity (800 mV/g @ 1.5g) Selectable Sensitivity (±1.5g, ±6g) Fast Turn On Time (0.5 ms Enable Response Time) Self Test for Freefall Detect Diagnosis 0g-Detect for Freefall Protection Signal Conditioning with Low Pass Filter Robust Design, High Shocks Survivability RoHS Compliant Use this library: mma7361-libraryHere's a sample sketch:Datasheet#include AcceleroMMA7361 accelero;int x;int y;int z;void setup(){ Serial.begin(9600); accelero.begin(13, 12, 11, 10, A0, A1, A2); accelero.setARefVoltage(3.3); //sets the AREF voltage to 3.3V accelero.setSensitivity(LOW); //sets the sensitivity to +/-6G accelero.calibrate();}void loop(){ x = accelero.getXAccel(); y = accelero.getYAccel(); z = accelero.getZAccel(); Serial.print("
