ESP32-IR(Infrared) SENSOR
Aim:
To extract information from IR sensor.
Description:
To learn how to
read values from an IR sensor using ESP32-Microcontroller.
Hardware required:
ESP32-Microcontroller
Development board,
IR sensor
Pin connection:

Procedure:
1.
The above pin connection shows how
to read values from a IR sensor using ESP32 board.
2.
Do the connections as shown in the pin diagram and
pin mapping.
3.
Connect the USB cable to the board.
4.
Open Arduino IDE .Select DOIT ESP32 DEVKIT V1 in
boards and select COM port.
5.
Verify the program and upload it.
6.
Now you can see the output on the serial monitor.
Program:
/* the setup
function runs once when you press reset or power the board */
void
setup(void)
{
/* initialize
digital pin 12 as an input */ pinMode(12,INPUT);
Serial.begin(9600);
}
/* the loop
function runs over and over again forever */
void loop(void)
{
int value=digitalRead(12);
if(digitalRead(12)==HIGH)
{
Serial.print("no obstacle:"); Serial.println(value); delay(1000);
}
else if(digitalRead(12)==LOW)
{
Serial.print("obstacle present:"); Serial.println(value);
delay(1000);
}
}
Output:
