Description:
This small 31x19 mm board is ready to be used out of the box. No parts
to be soldered. It is base on Three Axis Low-g Micromachined
Accelerometer from Freescale Semiconductor MMA7331L. The MMA7331L is a
low power, low profile capacitive micromachined
accelerometer featuring signal conditioning, a 1-pole low pass filter,
temperature compensation, self test, 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 MMA7331L includes a
Sleep Mode that makes it ideal for handheld battery powered electronics.
Features:
• Low Current Consumption: 400 μA
• Sleep Mode: 3 μA
• Low Voltage Operation: 2.2 V – 3.6 V
• Selectable Sensitivity (±4g, ±12g)
• Fast Turn On Time (0.5 ms Enable Response Time)
• Self Test for Freefall Detect Diagnosis
• Signal Conditioning with Low Pass Filter
• Robust Design, High Shocks Survivability
