Targeting the social fitness market,

STMicroelectronics (ST) has launched a smart motion sensor targeting the social fitness market.

Smart motion sensors enable continuous tracking applications to run for long periods of time and accurately record progress. The LIS2DS12 pico 3-axis accelerometer, LSM6DSL/M 6-axis inertial module, and LSM303AH eCompass perform motion-related calculations on-chip instead of using the main system processor, reducing the impact on the device’s battery life. The sensors include algorithms for high-precision pedometers, step detection and step counting, and key motion and tilt detection.




ST’s smart motion sensor is featured in some smartphones to power WeChat’s new messenger app WeRun. It also features an embedded FIFO, built-in self-test functions, an integrated temperature sensor, and programmable interrupts for conditions such as free fall, simplifying system design.

“WeRun brings physical activity into the social realm to help smartphone and wearable device users stay healthy,” said Andrea Onetti, Group Vice President and General Manager, MEMS Sensor Division, STMicroelectronics. “ST’s smart motion sensors allow WeRun to continuously track movement while conserving battery power.”

The LSM303AH is a digital compass with a built-in pedometer that is compatible with the WeRun app. It provides continuous walking monitoring and precise positioning using dead reckoning even in places where GPS signals are absent. We also created advanced software that facilitates user calibration of temperature drift and geomagnetic sensors.

ST said it can accelerate time to market by shortening the production time for app-based devices such as fitness bands, medical monitors, navigation, Internet of Things (IoT) nodes, smartphones, and wearables.
