VL53L0X – Failed to Detect and Initialize Sensor! Error

This issue is caused by power supply stability issues when starting up. By adding a once-off small delay in the setup section of your code allows for the power to stabilise before activating the VL53L0X sensor module.

An example of this is below:

void setup()
{
  delay(50);
  Serial.begin(9600);
  Wire.begin();

  sensor.setTimeout(500);
  if (!sensor.init() )
  {
    Serial.println("Failed to detect and initialize sensor!");
    while (2) {}
  }

The addition of the line “delay(50);” delays the initial activation of the sensor by 50 milliseconds, you can adjust the time to suit your needs and find what works best for you.
