VL6180X time-of-flight - distane and ambient light sensor I2C - Pololu 2489

Product description: VL6180X time-of-flight - I2C distance and ambient light sensor - Polol 2489.

A digital sensor that combines proximity measurement and the ability to measure ambient light. It operates up to 10 cm with a resolution of 1 mm. It is powered from 2.7 to 5.5 V, has a built-in voltage regulator and communicates via the I2C bus.

The time-of-flight method is based on measuring the time from the emission of an infrared laser pulse to its return to the detector. It is independent of light reflection from the object.

The module has passive elements necessary for the proper functioning of the system. The outputs are popular goldpin connectors, which enable the sensor to be connected bywires ordirectly connected to thecontactplate. The connectors are included in the set for self-soldering.
