STMicroelectronics has revealed a new FlightSense multi-zone distance sensor VL53L7CX that has native 64-zone (8 x 8) sensing and can measure distance to multiple objects in each zone, up to 350cm. These optical sensors bring lifelike situational awareness to applications like home automation, domestic appliances, computers, robots, and smart equipment used in stores, factories, and more. This sensor extends the field of view to an unprecedented 90° (diagonal) for enhanced peripheral sensing, almost equivalent to that of a camera.


This new sensor enhances the performance of applications like smart waste-management for tracking full and empty bins. It can also improve floor sensing, cliff prediction, obstacle avoidance, and small-object detection for robots. Further applications include keystone correction in projectors and extended hand tracking for gesture recognition using the STGesture™ software pack.


In low-power mode, the sensor consumes just 5.4mW. In addition, the VL53L7CX sensor can operate in autonomous mode that allows the host system to power down and wake only when a threshold value is reached. Thresholds include distance to nearest object, signal rate, and detection of motion. The new sensor is pin-to-pin and driver compatible with the previous-generation device, VL53L5CX.
