Maxim Integrated Products, Inc. has launched the next generation of its infrared-based dynamic optical sensor, which senses a broader range of gestures at extended distances. The MAX25405 doubles the sensing range to 40 cm when compared to earlier generations, in a quarter of the size. It also offers a 10× lower cost than time-of-flight (ToF) camera-based systems in automotive, industrial, and consumer applications, said the company.

The MAX25405, in a 20-pin, 4 × 4 × 1.35-mm quad flat no-lead (QFN) package together with four discrete LEDs, is up to 75 percent smaller than ToF camera-based solutions that require three chips and a microprocessor, according to Maxim.
The MAX25405 with integrated optics and a 6 × 10 infrared sensor array recognizes nine gestures, including swipe, rotation, air-click, linger to click and 3 × 2 proximity zones with minimal lag time. As a lower cost single chip, compared to ToF camera-based systems, the device offers more affordable gesture-sensing for a range of automotive, consumer, and industrial applications, including touch-free smart home hubs and thermostats, said the company.

In addition, the gesture sensor now includes a glass lens which is said to increase sensitivity and improve the signal-to-noise ratio. The improved performance doubles the proximity and distance of sensing applications beyond the driver to the car passengers.
These enhancements offer an alternative to voice communications, enabling drivers to focus on the road, while offering gesture-sensing entertainment displays to passengers, as an example, said Maxim.
The MAX25405 gesture sensor and MAX25405EVKIT# evaluation kit are available now from Maxim Integrated and authorized distributors.
