Low-power microcontrollers accelerate prototyping for sensor hubs
Small, low power microcontrollers (MCUs) in the RL78/G11 group will enable users to easily and more quickly prototype and develop systems that support low-power sensor hubs and sensor application systems, says Renesas Electronics. Sensor hubs are designed to connect to multiple sensors and convert the sensor output signals to digital data, and are used in computer operating environment monitoring for data centre thermocouples in the industrial area, wearable health management devices in the healthcare field, and environmental sensing in greenhouses and factory farms in the agricultural industry.
Smallest nine-axis motion sensor is compact for smart watches
Housed in a compact 2.5 x 3.0 x 0.95mm3 package, the BMX160 is the smallest nine-axis motion sensor in the industry, claims Bosch Sensortec.
Magnetic sensor reduces power consumption and processing time
Designed for portable devices, the MMC3630KJ, is a small, BGA package, magnetometer, from Memsic. The magnetometer integrates a monolithic, three-axis AMR sensor and signal conditioning ASIC and is based on the company’s proprietary technology. The BGA package measures 1.2 x 1.2 x 0.5mm. It has a range of ±30G range, and more than five times better noise level compared to other technologies, says the company. With 600Hz magnetic sensing bandwidth, the magnetometer provides better than 10 accuracy in eCompass applications. The design also has drastically lower system level power consumption and processing time, claims the company. There is also a self-degaussing feature, which can eliminate the output drift due to temperature change and residual magnetic from ambient magnetic field. The series also includes an interruption feature, which can be used for motion detection and data acquisition ready notifications to lower system-level power consumption. http://www.memsic.com
