From left to right are numbered 1,2,3,4 . They are defined as follows :

l 1No. Pin: connected to VCC power supply ( DC 5V).

l 2No. Pin: Range setting pins (Range), when the module is powered up this pin is high , the range of 3m; when the module is powered up this pin is low , the range of 1m. Within this pull- pin , pin floating when the Range , the range of 3m.

l 3No. Pin: analog voltage output pin (Out), an analog voltage proportional to the distance measurement , the output range is 0 ~ Vcc.

l 4No. Pin: connect to an external circuit .

5 . Ranging works

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

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

Analog voltage proportional to the distance measurement range of the analog output voltage is 0 ~ Vcc.

When the system is 1m range , the measurement distance : L = 1024 * Vout / Vcc (mm). When the output voltage is 0V corresponds to a distance of 0m, the output Vcc corresponding to 1.024m.

When the system range is 3m, measuring distance : L = 3096 * Vout / Vcc (mm). When the output voltage is 0V corresponds to a distance of 0m, the output Vcc corresponding to 3.072m.

Measure the distance and output voltage relationship shown in Figure 5.1 :

6 . When programming recommendations range 1m

Note: When powered on, you need to Range pin low .

When measuring , the output voltage can be ADC Out pin is sampled , measured in terms of the distance according to ADC value to calculate the following formula can be used :

L = (A * 1024/2 ^n) *(Vref / Vcc), where A is the value of the ADC , n is the number of bits of the ADC , Vref to the ADC reference voltage , Vcc for US-016 of the power supply voltage .

For example, 10-bit sampling ADC and ADC reference voltage is VCC, measure the distance ADC values available to represent. Example: When the ADC sample is 345 , the measurement distance of 345mm.

When the range is 1m, ranging routines :

unsigned int ADCValue;

void setup ()

{

Serial.begin (9600);

}

void loop ()

{

ADCValue = analogRead (0);

Serial.print ("Present Length is:");

Serial.print (ADCValue, DEC);

Serial.println ("mm");

delay (1000); // delay 1S

}

7 . When programming recommendations range 3m

Note: When powered on, you need to Range pin is floating or set high.

When measuring , the output voltage can be ADC Out pin is sampled , measured in terms of the distance according to ADC value to calculate the following formula can be used :

L = (A * 3072/2 ^
