DFRobot Fermion: VL6180X ToF Distance Ranging Sensor embeds ST’s patented FlightSense™ technology that measures distance accurately independent of target reflectance. This sensor is rated to perform 5mm to 100mm ranging measurements and can provide up to 200mm readings in a good environment. The VL6180X distance-ranging sensor is equipped with an ambient light sensor that combines proximity-ranging and ambient light level measurement capacities into a single package. This sensor operates at 3.3V to 5V supply voltage range and -20°C to 85°C operating temperature range.
