Ranging principle

After the module is powered up, the system first determines the input level of the Range pin, and sets the different range according to the input level. When the Range pin is high, the range is 3m, when the Range pin is low, the range is 1m.

Then, the system starts with a continuous ranging, and the ranging results are output by simulating the voltage at the Out pin. When the distance changes, the analog voltage will also be changed.

The analog voltage is proportional to the 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, the corresponding distance is 0m, and the output Vcc is 1.024m.

When the system range is 3m, the measurement distance is: L = 3096*Vout/Vcc (mm). When the output voltage is 0V, the corresponding distance is 0m, and the output Vcc is 3.072m.

5. Ranging works

After the power module, the system first determines Range pin input level to set different ranges depending on the input level of the state.When the Range pin is high, the range is 3m, when the Range pin is low, the range is 1m.

Then, the system begins continuous ranging, while the ranging results in an analog voltage output pin Out. When the change in distance analog voltage will also vary.
