M5Stack Time-of-Flight Ranging Unit (VL53L0X)

ToF employs time-of-flight techniques to resolve the distance between the emitting point and the reach point of a subject, measuring the round trip time of an artificial light signal provided by a laser.

This unit integrated a distance measuring sensor VL53L0x providing accurate distance measurement whatever the target reflectance, unlike conventional technologies. It can measure absolute distances up to 2m in less than 30ms.

This unit communicates with M5Core via I2C(0x29). In this case, make sure you use the 3.3V on SDA and SCL, M5Core GROVE provides 3.3V to data pins, 5V to the power pin. only 3.3v allowed on VL53L0x.

Applications:

• 1D gesture recognition
• Laser Ranging
• 3D structured light imaging?3D sensing?
• Camera assist (ultra-fast autofocus and depth of field)
