[Training Camp] Simple Small Infrared Remote Control-340465A

Initial idea: Make a networked infrared remote control through the Tuya Cloud platform, and then look at the casing. If there is space, add other ideas.

  Limited by the shell, it has an infrared remote control function, which can learn remote control codes and be controlled by mobile phones. There is no corresponding smart speaker and no language remote control.

Main material:

  Tuya WB3S module serves as the main control, two SMD infrared transmitting tubes and one 5mm infrared transmitting tube serve as remote control transmitting signals, one 1838B serves as the receiving head for learning remote control, and the linear voltage regulator provides power.

Conditions of Use:

  UISB power supply 0.5 rupees, 2.4G band WiFi

I've been using it for a few days and it's still fine. PCB diagram

The standby current is 24mA, and it will jump to 120mA when transmitting (it may not be accurate, I will buy a unit to measure the current in the future)

Finished product appearance

Here, because I want to save one pull-up from passing under the antenna, I pull it up to the power supply of the infrared receiver.

The user experience is that it can be easily plugged into the USB. The emission angle on the front and back sides of the PCB is 120°, and the infrared emission tube is directly inserted at 80°. It's no problem being one room away, and it's very convenient for network distribution and so on.

Summary: Using the Tuya 0-code solution, you only need to configure the pins and modify them according to the reference schematic diagram to use it. After placing the order, the module firmware becomes a single product, suitable for mass production. It can be done directly by SMT, and no configuration download is required.

For developers, the development cycle is short and the development difficulty is low.
