ST’s LSM6DSV320X – An AI-enabled IMU with two MEMS accelerometers for activity and shock detection

STMicroelectronics has introduced the LSM6DSV320X, a compact AI-enabled inertial measurement unit (IMU) that integrates a 3-axis digital gyroscope, a 3-axis low-g accelerometer (±16g), and a 3-axis high-g accelerometer (±320g) in a tiny 3 x 2.5mm package, ideal for space-constrained IoT devices such as wearables, smartphones, gaming controllers, smart tags, personal safety gear, and industrial monitoring systems. Most motion sensors are designed to track daily activities or detect sudden impacts, but the LSM6DSV320X is built to do both. One accelerometer tracks everyday motion up to ±16g, while the other handles high-impact events up to ±320g. One of the most interesting features is its adaptive self-configuration (ASC), which allows real-time adjustment of internal settings based on activity without the need for a host CPU, optimizing power use and responsiveness. It also includes a machine learning core (MLC) capable of running up to eight decision trees and a finite state machine (FSM) to […]

UV Meter for Flipper Zero measures ultraviolet radiation with AS7331 sensor

The UV Meter is a Flipper Zero application designed to measure ultraviolet (UV) radiation using the AS7331 spectral sensor, which can detect UV-A, UV-B, and UV-C wavelengths. Designed for personal and environmental UV monitoring, this tool measures UV exposure levels in everyday scenarios, whether it’s behind windows, under cloud cover, or while wearing sunglasses. It provides real-time irradiance readings in µW/cm², W/m², or mW/m², and calculates safe maximum daily exposure durations based on 2024 TLVs and BEIs from ACGIH, with adjustable factors like eye protection status, gain, and exposure time. A visual meter and warning symbols notify the user of under- or overexposure. The app also displays each UV type’s relative contribution to overall exposure risk. A compact adapter PCB enables easy connection between the Flipper Zero and the AS7331 breakout board via I²C. Flipper Zero UV Meter specifications: Target platform – Flipper Zero Sensor module – Sparkfun AS7331 Spectral […]
