The VL6180x three-in-one optoelectronic module integrates an IR VSEL (vertical-cavity surface-emitting laser) infrared vertical cavity surface emitting laser source, proximity sensor, and ambient light sensor (ALS).
The VL6180X module implements a proximity sensor using the time-of-flight (ToF) measurement principle; the VL6180X includes a SPAD (Single Photon Avalanche Diode) detector array that detects the time at which a single photon is transmitted from the target to the target and back to the module, calculated in conjunction with the signal amplitude. The actual distance, independent of the reflectivity of the object, this actual distance measurement capability can also produce simple but reliable one-dimensional gesture control.
The ambient light sensor also has high sensitivity and precision under ultra-low light, wide sensing dynamic range, and ambient light (Lux) corrected output.

Pinouts:
-
Vin: Power input pin. Voltage input range 3-5V
-
2v8: Output port, output 2.8V voltage, the 2.8V output voltage generated by the on-board voltage regulator processing VIN input voltage, convenient to expand and use
-
GND: power ground
-
SCL: I2C clock pin, connected to the master SCL
-
SDA: I2C data pin, connected to the master SDA
-
GPIO: The pin used by the sensor to indicate that the data is ready. Note that the output of this pin is 0-2.8V high and low. This pin may not be applied to boards such as Arduino (these boards are 3.3 or 5V high). ), generally not used, to apply level conversion
-
SHDN: The shutdown pin of the sensor. By default it is pulled high. There is a level shifting diode so you can use 3-5V logic on this pin. When the pin is pulled low, the sensor enters the shutdown mode.
