ST LIS302ALK Motion Sensor

STMicroelectronics LIS302ALK is a tiny, low-power MEMS device that provides precise acceleration values in all three dimensions. The analog-output LIS302ALK provides individual acceleration values for all three (x, y, z) axes. The sensor is housed in a 5 x 3 x 0.9 mm plastic package to fit in a variety of space-constrained applications and its ultra-compact robust design provides shock survivability up to 10,000g in 0.1 msec.

The new sensor offers a full-scale output range of +/-2.0g and it is suitable for low-frequency vibration monitoring at very low power consumption. It incorporates a power-down mode to reach 1uA supply current and built-in self-test capability that allows the customer to verify the functioning of the sensor after it has been assembled on board.

ST’s LIS302 family of motion sensors can also be used to manage power consumption of products that need to be powered on (or off) while or after they have been touched or moved. For example, motion sensors can activate a remote control when someone picks it up, controlling the overall power consumption of the circuitry. In medical applications, the sensors can be used to monitor motion or detect the position/activity level of patients.

Unit pricing is $2.95 for quantities of 30,000 pieces.
