示例代码
方案一
/* description: The sample code is used to measure distance by GP2Y0A02YK IR ranger sensor. VCC -- VCC GND -- GND Signal -- Analog 1 */ int IRpin = 1; // analog pin for reading the IR sensor void setup() { Serial.begin(9600); // start the serial port } void loop() { float volts = analogRead(IRpin)*0.0048828125; // value from sensor * (5/1024) - if running 3.3.volts then change 5 to 3.3 float distance = 65*pow(volts, -1.10); // worked out from graph 65 = theretical distance / (1/Volts) Serial.println(distance); // print the distance delay(100); // arbitary wait time. }
