3-axis accelerometer
Digital 3-axis accelerometer based on the Freescale MMA8452Q sensor
SKU 2846-MMA8452EAN 8219671080774Item type: AssembledSensors, Sensors
Description
3-axis digital accelerometer based on the Freescale MMA8452Q sensor. Measurement ranges 2g, 4g, and 8g, power supply: from 3.6 VDC to 5 VDC, consumption: max. 165 µA. It features two programmable interrupt pins, automatic sleep and wake-up modes, and signal conditioning with a high-pass filter. It integrates a level shifter for the SDA and SCL lines to adapt the 3.3V levels of the IC to the communication levels used to talk to the MMA8452 (max. 5V). Dimensions (mm): 23×16.6. The board is supplied already assembled and tested.
