This site that gives a sense of what’s happening in the world of sensor technology and helps designers to stay current with new trends, good technological ideas, novel materials, and products. Optimum and robust design ideas combined with innovative techniques showing how-to-interface and condition sensor outputs are some of the areas explored. Mathematical aspects of sensor accuracy, temperature, and linearization tracking and correction are some of the many and varied areas to be explored.

Adaptive headlights solve fixed-beam challenges

Headlight controls are often limited by a fixed beam direction that can only be switched between high beam and low beam. This makes it difficult to drive when there are multiple turns on the road or when the slope of the road changes. Here’s a low cost and adaptive solution. Read More...

Ultra-low power system for wearable devices

While the brains of the typical wearable device might be the embedded microcontroller (MCU), the heart is definitely with power management. Extremely small capacity batteries, diverse array of functions needing power, and the incredibly small solution size force new and innovative power management solutions to make the system work well. But when an ultra-low power optimized MCU and ultra-low power optimized DC/DC converter come together, the result is a well-running, well-oiled machine fit for wearable applications. Read More...
