WWH-Triple Axis Accelerometer MMA7361

Introduction The MMA7361 from Freescale is a very nice sensor with easy analog interface. The MMA7361 is a 3.3V part and outputs an analog voltage for each of the three outputs. This voltage is in ratio to the measured acceleration and to the supply voltage (ratiometric). It has selectable sensitivity by dip switch. You will need some extra hardware to convert this analog signal to a usable digital one. The Arduino is really good option for it. This break board is especially designed for Arduino which has 3 JST connector that can be easily plug into our IO/Sensor expansion board. Notice:The new version of analog sensor port pin mapping has been changed as the following two features.Please check the tips for changing sensor cable pin mapping while using the I/O Expansion shield. We will continue to update. For the inconvenience caused, please understand. Applications Measure the acceleration information for your robot or other devices Using for slope alarm or other kinds of alarm such as shock Improvement List Standard assembling structure (Times-of-5mm Center distance between two 3mm mounting holes) Easily recognitive interfaces of sensors ("A" for analog and "D" for digital) Icons to simplely illustrate sensor function High quality connector Immersion gold surface Specification Voltage:3.3-8V Selectable sensitivity:±1.5g/6g Low power:500µA @ measurement mode,3µA @standby ; High sensivity: 800 mV/g @ 1.5g; Interface:Analog Output Low pass filter Size:26*37mm Weight: 15 gram
