**Details** This Tibbit is based on the ADXL312 accelerometer IC with I2C interface. The sensor is implemented as the [C1 device](http://docs.tibbo.com/phm/tibbit_c1.htm). The module measures acceleration in the +/-12G range, simultaneously in three axes, and with 2.9mG resolution. This C1 device requires the Tibbit #00-3 to be installed in the neighboring ["M" Tibbit socket](http://docs.tibbo.com/phm/the_standard_tibbit_tile.htm). #00-3 provides two direct lines for I2C comms, as well as the ground and +5V power for the ADXL312 IC. **Sample project** The use of this Tibbit is illustrated by a Tibbo BASIC test project.
