Bosch Sensortec seeks to cut back on the upgrades and replacement of parts on the internet of things (IoT) and industrial markets with the introduction of new micro-electro-mechanical systems (MEMS) sensors that feature a longer lifespan.
Bosch introduced the series of long lifespan sensors under its Longevity Program last month due to products in these markets usually having longer design cycles than internet connected devices such as smartphones or wearables. Upgrades and replacements of industrial machinery or appliances is costly if new components need to be requalified. However, the Longevity Program offers a higher level of reliability and predictability as the same product used during the initial design, lowering the risks and costs for designers, Bosch said.
Bosch told Electronics360 that its customers were always interested in sensors for specific use cases but requested longer availability of the products. With the increasing roll out of artificial intelligence (AI) and 5G, demand is expected to grow significantly in the Industry 4.0 market. For industrial use cases, sensors are the core of smart industrial applications such as asset tracking and predictive maintenance, and expanding the market to allow for a greater lifespan meets the needs and requirements specific to IoT and industrial designers, the company said.
The new longevity MEMS include the BMI090L inertial measurement unit (IMU), the BMA490L accelerometer and the MPB390L barometric pressure sensor.
The BMI090L IMU is designed for the IIoT, robots, agricultural equipment and drones as well as white goods and home appliances. It features vibration robustness and temperature stability as well as use cases for navigation and motion- and asset-tracking.
The BMA490L accelerometer serves the same markets as the IMU with the addition of power tools. The sensor features temperature stability, low noise and low offset for use cases such as predictive maintenance, asset tracking and vibration monitoring.
The BMP390l barometric pressure sensor offers temperature stability of typically ±0.6 Pa/K and a typical relative accuracy of ±0.03 hPa for use cases such as water level detection, asset tracking and navigation.
Beyond just having a long lifespan, the BMI090L IMU, BMA490L acceleration sensor and the BMP390L barometric pressure sensor improve on performance, robustness and stability to meet the requirements of the industrial market. Additionally, the sensors offer a 10-year availability and increased purchasing flexibility due to smaller reel sizes.
