Regarding the infrared remote control function, the default is LeTV TV remote control with universal remote control on mobile phones. You can also record the address of other TV infrared remote controls (NEC protocol, if it displays EE or no response, the remote control protocol does not match) by flashing the Ir_test program in the attachment. Modify the main program Divergence Meter_demo/IrData.H after adding the key value. When programming, select the IRC frequency as 12MHz, otherwise the infrared clock frequency will not match.

The M and S buttons have not yet added functions.

Screws: M3*7+4 single-head stud x2, M3*22 double-way stud x2, M3*5 flat head hexagon socket screw x4

The connecting pins on the upper and lower boards and the infrared receiving sockets are not ordinary pin headers, but the pins and pin sockets of 2.54mm round pin headers after removing the fixing plastic.

Battery: 18650x2 (parallel)

Note: Due to the VFD heating, the temperature and humidity meter will be inaccurate after a period of power-on.

There’s not much else to say. I dug a hole last year and the program was poorly written. I’ve been busy recently and haven’t filled the hole yet. Please refer to it for reference.

Chips are ridiculously expensive now. . .
