Because the sensor relies on light reflection, surface color and texture drastically impact performance: The is an affordable, highly efficient infrared obstacle
Lights up immediately when the module receives power.
Includes an onboard "blue trim pot" used to adjust the sensor's sensitivity/range. Pin Configuration
Potentiometer sensitivity is set too high, or ambient sunlight is interfering.
