Obviously my Samsung TV uses the protocol and chip from Samsung, and my Set-top box turn out to be using NEC format.

The sketch print out the IR code for each key in hexdecimal as well as the protocol used by the different vendor of the IR chip.

When this sketch is run in ESP32, we can monitor the data on the serial terminal for each key pressed on a remote. Irrecv.resume() // Receive the next value The following sketch is used to decode the data from each key of a TV remote.Ĭase SONY: Serial.println("SONY") break Ĭase DISH: Serial.println("DISH") break Ĭase SHARP: Serial.println("SHARP") break Ĭase SANYO: Serial.println("SANYO") break Ĭase MITSUBISHI: Serial.println("MISUBISHI") break Ĭase SAMSUNG: Serial.println("SAMSUNG") break Ĭase WHYNTER: Serial.println("WHYNTER") break Ĭase AIWA_RC_T501: Serial.println("AIWARC_T501") break Ĭase PANASONIC: Serial.println("PNASONIC") break Ĭase DENON: Serial.println("DENON") break Ĭase UNKNOWN: Serial.println("UNKNOWN") break The IR receiver that I have matched the PNA4602 pinout shown below. ESP32 pin map for Arduino core can be find at Arduino core for the ESP32 github page. Decoding IR codes of TV/Set-top box remotesĪn IR receiver usually has three pinouts as shown in the picture, I connect the Vout to ESP32 GPIO15, Vcc to ESP32 3.3v, and GND to ESP32 GND. An IR receiver usually consists of a photo detector and signal demodulator in a single package and the output can be directly used by a microcontroller. The IR receiver is not used in this project but will be needed temporarily for decoding the IR codes of existing TV and Set-top box remote. The infra red code representing each button (such as TV on/off, mute, volume up and down, etc.) is typically modulated using pulse width modulation with a carrier frequency (typically 36, 38, or 40KHz depend on different protocols) before sending through the infra rad transmitter. The IR transmitter is typical a infra red diode capable of emitting a beam of light, typically at 940nm (840nm also available) wavelenth. The IR transmitter will be used by the ESP32 to send the signal to control the TV/Set-top box. IR diode and receiver from an old set-top box I get a pair of IR transmitter and receiver (plus a few useful components) from an old Set-top box and remote that was retired from analog TV era a few years ago.

System diagram of ESP32 Web Server/IR Remote Although it has nothing to do with the remote control functionality or infra red communication, but I do it just because I want to use the spare SHT21 sensor, and the ability to know my room temperature and humidity when I using the remote is kind of cool. As I also have a SHT21 temperature/humidity sensor breakout board, I decided to add it to the ESP32, so that when I access the web page, it also display the current temperature and humidity information. Here is the idea, I want to replace my TV and Set-top box remote controls with my own controller made of an ESP32, which will have an IR transmitter that communicating with the TV (and Set-top box which currently has a separate IR remote), the ESP32 also running as a web server so that a web page can be accessed via an iPhone to control the TV/Set-top box from the on-screen virtual keypads. My TV remote control is corroded by leaking battery and no longer working reliably, so I decided to build my own TV remote control with an ESP32 that running as a web server and IR remote control so that I can uses my iPhone to interactive with it via web browser.
