How Ranging Works

After the module is powered on, the system first judges the input level of the Range pin, and sets different ranges according to the state of the input level

When the Range pin is high level, the range is 3m, when the Range pin is low level, the range is 1m.

Then, the system starts continuous distance measurement, and at the same time outputs the distance measurement result on the Out pin through the analog voltage. when the distance changes

The analog voltage will also change accordingly.

The analog voltage is proportional to the measurement distance, and the output range of the analog voltage is 0~Vcc.

When the system range is 1m, the measurement distance is: L = 1024*Vout/Vcc (mm). When the output voltage is 0V corresponding distance

is 0m, the output Vcc corresponds to 1.024m.

When the system range is 3m, the measurement distance is: L = 3096*Vout/Vcc (mm). When the output voltage is 0V corresponding distance

is 0m, the corresponding output Vcc is 3.072m.

The relationship between measurement distance and output voltage is shown in Figure 1:

Programming suggestion when the measuring range is 1m
Note: When powering on, the Range pin needs to be set to low level.

During measurement, an ADC can be used to sample the output voltage of the Out pin, and the measurement distance can be converted according to the ADC value, which can be used as

Formula calculation:

L = (A*1024/2^ n )* (Vref/Vcc), where A is the value of the ADC, n is the number of bits of the ADC, and Vref is the parameter of the ADC

Voltage, Vcc is the power supply voltage of US-016.

For example, when a 10-bit ADC is used for sampling, and the reference voltage of the ADC is VCC, the measurement distance can be expressed by the value of the ADC.

Example: When the ADC sampling value is 345, the measurement distance is 345mm.

When the range is 1m, the Arduino ranging routine:
