VL53L0X Time of Flight Distance Sensor (2m Range) rtd A pH less than 7

A pH less than 7 is said to be acidic and solutions with a pH greater than 7 are basic or alkaline

This enables the use of current limiting resistors tointerface inputs to voltages in excess of VCC

VL53L0X Time of Flight Distance Sensor (2m Range) rtd A pH less than 7Introduction : This sensor is a carrier breakout board for STs VL53L0X laser ranging sensor, which measures the range to a target object up to 2 m away. The VL53L0X uses time of flight measurements of infrared pulses for ranging, allowing it to give accurate results independent of the targets color and surface. Distance measurements can be read through a digital IC interface. The VL53L0 uses STs FlightSense technology to precisely measure how long it
