Firgelli Robots Three-axis Analog Accelerometer Sensor

Three-Axis Analog Accelerometer Sensor


Three-axis Analog Accelerometer Sensor


The MMA7361LR1 is a low power, three-axis analog accelerometer. The sensor has a g-Select input which allows for the selection between two measuring ranges ±1.5g or ±6g.

Other features include signal conditioning, a 1-pole low pass filter, temperature compensation, self test, and 0g-detect which detects linear free-fall. Zero-g offset and sensitivity are factory set and require no external devices. The MMA7361L also includes a sleep mode.

The sensor works on power between 2.2 and 3.6VDC (3.3V optimal), and typically consumes just 400µA of current. All three axis have their own analog output.
