| Pin | Function |
| D0 | data pin |
| D1 | data pin |
| D2 | data pin |
| D3 | data pin |
| +9V | positive power supply |
| GND | negative power supply |
Operation:
1. Connect the positive pole of the DC 9V power supply to the "+9V" pin of the transmitter module.
2. Connect the negative pole of the DC 9V power supply to the "GND" pin of the transmitter module.
3. Connect any data pin of the transmitter module's "D0" ~ "D3" pin to the "+9V" pin. Then it will transmit the corresponding signal.
