加速度计测量线性加速度。也可用于特定目的,例如:倾斜度和振动测量。MEMS加速度计嵌入了一些用于运动和加速度检测的有用功能,包括自由落体、唤醒、单次/两次轻击识别、活动/不活动检测以及6D / 4D方向。

我们的加速度计产品组合

加速度计

意法半导体的先进3轴MEMS加速度计包含模拟和数字部分,加速度(量程)高达±400g、电源电压为1.71~3.6V。

完美适用于低功率应用场合

意法半导体的加速度计传感器具有先进的节电特性,是超低功耗应用的理想之选。这些特性包括低功耗模式、自动唤醒功能和可用于存储数据的FIFO缓存,从而降低了主处理器负载和系统功耗。

它们适于便携式应用(例如手机和PDA),同时满足低功耗与小尺寸的应用。意法半导体最近推出的新一代加速度计在小型化方面取得了巨大进步,封装尺寸仅为2x2x1 mm,并且提供2种管脚选项:14和12引线。

用于汽车应用和工业应用

New IIS3DWB sensing solution for wide scale adoption of vibration monitoring in Industry 4.0 applications

Optimized for high performance industrial vibration sensing, the 3-axis IIS3DWB MEMS accelerometer with an ultra-wide bandwidth and low-noise is a power-efficient and affordable digital sensing solution included in ST’s 10-year longevity program.

The IIS3DWB sensor is a key enabler of industrial vibration monitoring:

· it offers a 3-axis digital plug-and-play solution for a seamless and cost-effective adoption

· its wide and flat frequency response up to 6kHz and low noise ensure high-quality vibration data is collected

· the sensor low-power and extended temperature range up to +105°C is ideal for long-lasting, self-powered wireless sensor nodes and allows them to be retrofitted into existing systems

The STEVAL-STWINKT1 development kit takes the prototyping of vibration monitoring solutions to the next level by integrating the IIS3DWB sensor with numerous additional sensors and an ultra-low-power STM32L4+ MCU, and offering wired and wireless connectivity. Software libraries for vibration processing are also available, including a high-speed data logger for data scientists to develop algorithms.
