Infrared (IR) technology is widely used in remote controls, automation systems, and IoT devices. In this TSOP ESP32 tutorial, you will learn how to connect a TSOP IR receiver sensor with ESP32 and decode signals from any IR remote control. This TSOP ESP32 tutorial will guide you through the setup process, ensuring you understand how to utilize the TSOP ESP32 tutorial effectively.

What is a TSOP Sensor?

Understanding the TSOP ESP32 tutorial is crucial for anyone interested in developing IoT projects. It helps you explore the full capabilities of the TSOP ESP32 tutorial, making your projects more interactive.

Infrared communication is a simple yet effective way to transmit data wirelessly. IR signals are modulated to carry information, which the TSOP sensor can decode. This modulation typically occurs at a frequency of 38kHz, allowing the sensor to filter out other signals and focus solely on the IR data from the remote control.

A TSOP sensor (e.g., TSOP1838) is an IR receiver module that detects infrared signals and converts them into digital output readable by microcontrollers like ESP32.

Features:

• Operates at 38kHz frequency
• Built-in noise filtering
• Low power consumption
• Easy integration with ESP32

Arduino Code (ESP32 + TSOP IR Decode)

#include <IRremoteESP8266.h>
#include <IRrecv.h>
#include <IRutils.h>

const uint16_t RECV_PIN = 5;  // GPIO5 for ESP32

IRrecv irrecv(RECV_PIN);
decode_results results;

void setup() {
  Serial.begin(115200);
  irrecv.enableIRIn();  // Start receiver
  Serial.println("IR Receiver Ready...");
}

void loop() {
  if (irrecv.decode(&results)) {
    
    Serial.print("IR Code: ");
    Serial.println(results.value, HEX);

    // Optional: detailed decode info
    Serial.println(resultToHumanReadableBasic(&results));

    irrecv.resume();  // Receive next value
  }
}
