Using two IR sensors with an Arduino allows you to detect objects or motion from multiple directions. This setup is common in robotics, automation, and counting systems.
Wiring Setup
IR Sensor 1: VCC ā Arduino 5V, GND ā Arduino GND, OUT ā Arduino D2
IR Sensor 2: VCC ā Arduino 5V, GND ā Arduino GND, OUT ā Arduino D3 Ensure both sensors share the same ground for stable readings.
Arduino Code Example The following code initializes two IR sensors and prints their status to the Serial Monitor:
int IR1 = 2; // First IR sensor on pin D2int IR2 = 3; // Second IR sensor on pin D3void setup() {Serial.begin(115200);pinMode(IR1, INPUT);pinMode(IR2, INPUT);}void loop() {int sensor1Status = digitalRead(IR1);int sensor2Status = digitalRead(IR2);if (sensor1Status == LOW) {Serial.println("IR Sensor 1: Object Detected");} else {Serial.println("IR Sensor 1: Clear");}if (sensor2Status == LOW) {Serial.println("IR Sensor 2: Object Detected");} else {Serial.println("IR Sensor 2: Clear");}delay(200); // Small delay for stability}Gekopieerd.āKopiëren Arduino UNO Based Dual IR Sensor Circuit | Cirkit Designer
