Description

Have you ever come back to your office from outside and wanted to turn on the air conditioner to cool down, only to find that the remote control is missing? It's frustrating, especially during the summer. To solve this problem, I decided to make a smart air conditioner terminal using an infrared module. I collected all the information from the air conditioner remote control on my development board, and used it to control the air conditioner through the infrared module. The terminal also displays the current temperature and humidity, so I can know the environment's conditions. Plus, I won't lose the remote control anymore because I fixed it on the wall. Now, let me share with you how I made it

Supplies

1. The ESP32 Display-5.0 Inch is used as the main control board to control the infrared module and read temperature and humidity information from the sensor. It can also display the user interface designed with LVGL on the screen for human-machine interaction.

2. The Crowtail-AM2302 Humidity & Temperature Sensor 2.0 is used to help me obtain the temperature and humidity information of the surrounding environment, which is then transmitted to the main control board via IO port.

3. The Infrared Transceiver Module is used to help me receive and record the infrared signals sent by the air conditioner remote control. It can also transmit the recorded infrared signals to the air conditioner via infrared emission. This enables my main control board to easily control the air conditioner.
