MAX25405 Infrared-Based Dynamic Gesture Sensor Detects Broad Range of Hand Gestures at Greater Distances to Ensure Safety on Road

Maxim Integrated Products has introduced the next generation MAX25405 infrared-based dynamic optical sensor that detects wider proximity of movement and doubles the sensing range to 40cm when compared to earlier generations, in a quarter of the size and at 10x lower cost than time-of-flight (ToF) camera-based systems in automotive, industrial and consumer applications.This new sensor with enhanced features is a smart alternative to voice communications thus enabling drivers to focus on the road.

Along with integrated optics and a 6 x 10 infrared sensor array, the next-generation MAX25405 now includes a glass lens which increases sensitivity and improves the signal-to-noise ratio. The improved performance doubles the proximity and distance sensing applications to beyond the driver, offering gesture-sensing entertainment displays to the co-driver and rear seat passengers, for example. The MAX25405 features a high level of integration compared to competitive ToF solutions that require three chips and a complicated microprocessor. The MAX25405’s small20-pin, 4mm x 4mm x 1.35mm quad flat no-lead (QFN) package together with four discrete LEDs measures upto 75% smaller than ToF camera-based solutions.

Key Advantages 

• Wide sensing range: The MAX25405 senses a wider proximity of movement and doubles the sensing range from 20cm to 40cm when compared to earlier infrared generations.

• Lowest cost and smallest size: The MAX25405 senses swipe, rotation and other important gestures at a lower cost than ToF cameras. High integration results in a total solution size that is significantly smaller than ToF camera solutions.

• Versatile:The MAX25405 recognizes nine gestures, including swipe, rotation, air-click, linger to click and 3x 2 proximity zones with minimal lag time. This cost-effective single chip makes gesture-sensing affordable for multi-range automotive, consumer and industrial applications, including touch-free smart home hubs, thermostats and many more.
