Description PWM output, you can set the frequency, duty cycle; Frequency is divided into four ranges, automatic switching: 1. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz; 2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz; 3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz 4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz e.g. frequency display: 100 indicates PWM output 100Hz pulse; 1.01 indicates PWM output 1.01K pulse; 54.1 indicates that the PWM output has a pulse of 54.1 kHz; 1.2.4 indicates that the PWM output is 124 kHz pulse; Duty cycle range: 0 ~ 100%;

The GP2Y0A41SK0F Sharp analog distance sensor features a detection range of 1.5″ to 12″ (4 cm to 30 cm). The shorter range gives you higher resolution measurements, and the lower minimum detection distance makes this sensor great for detecting very close objects. The distance is indicated by an analog voltage, making this sensor very easy to use.
