Simple code:
#include <SONAR.h> //used the library of SONAR
// The sonar whose address is 0x11 was named S11, and it was setted as the type of SONAR
SONAR s11=SONAR(0x11);
//SONAR s12(0x12);
void setup() {
SONAR::init(); //set up some parameters
delay(100); //100 millissecond
s11.setAddr(0x11); //set address for S11with 0x11 .
}
//Ttrigger sonar and display the data.
void loop() {
s11.trigger(); //Send the trigger command to trigger S11
//s12.trigger();
delay(SONAR::duration); //60 millissecond.
Serial.println(s11.getDist(),DEC); //Display the distance S11 received.
s11.showDat(); //Display the data S11 received
//Serial.println(s12.getDist(),DEC);
Serial.println(s11.getTemp(),DEC); //Display the temperature S11 received
//Serial.println(s12.getTemp(),DEC);
delay(500);
}
¾ Sensor Connection
As the sensor uses RS485 interface which can not be connected directly to the MCU, a MAX485 chip will
bridge the TTL interface to RS485.
For PC users, either a USB-RS485 or RS232-RS485 converter will bridge the gap.
¾ Sensor Networking
Up to 32 units are able to join a RS485 network. Simply serially connect the sensors uses twisted pair
cables.
