Maxim improves IR sensor for gesture detection
The company claims it does this in one quarter of the size and one tenth the cost of time-of-flight (ToF) camera-based systems in automotive, industrial and consumer applications. These enhancements offer an alternative to voice communications, enabling drivers to focus on the road.
The MAX25405 recognizes nine gestures, including swipe, rotation, air-click, linger to click and 3 by 2 proximity zones. Along with integrated optics and a 6 by 10 infrared sensor array, the MAX25405 includes a glass lens which increases sensitivity and improves the signal-to-noise ratio.
The MAX25405 comes in a 20-pin, 4mm by 4mm by 1.35mm quad flat no-lead (QFN) package together with four discrete illuminating LEDs.
The MAX25405 gesture sensor and associated evaluation kit are available now from Maxim and authorized distributors.
