This product is no longer supported. Please have a look at the MLX75123BA companion chip.

The MLX75123 is a fully integrated companion chip for Melexis’ Time-of-Flight (TOF) sensors. It’s perfectly suited for automotive and non-automotive applications, including, but not limited to, gesture recognition, driver monitoring, skeleton tracking, people or obstacle detection and traffic monitoring.

This sensor interface is designed to connect directly to any Melexis TOF sensor and the output can be directly connected to a camera parallel port and I2C interface of a microcontroller.

Occupancy and steering wheel hands on/off detection (side view)

Application

This demo presents a Time-of-Flight (non-capacitive) steering wheel hands on/off detection, body pose, movement and occupancy detection, which can address solutions that support partially to fully autonomous driving. The Time-of-Flight camera is positioned near the roof module and the 3D view is rotated to show a side view of the driver.

Real-time body pose detection (frontal view)

Application

This demo shows detection of the driver hand(s) on the steering wheel as well as a body pose detection, which can address solutions that support partially to fully autonomous driving. The Time-of-Flight (ToF) camera is positioned near the roof module and the 3D view is rotated to show a frontal view of the driver.
