Pin Definition (5 Pin, same as ZE03 series standard pins)
| Pin | Definition | Explanation |
| --- | --- | --- |
| VCC | Power Supply | DC5V |
| GND | Power Ground | Common Ground |
| TXD | Module Transmission | Connect to the microcontroller's RX (3.3V level, direct connection to 5V IO is prohibited) |
| RXD | Module Reception | Connect to the microcontroller's TX |
| VO | Analog Voltage Output | 0-3V analog signal |
Output Explanation
1. UART Serial Port (Preferred) **: Directly outputs HF concentration (one decimal place), module temperature, fault status; supports command reading and address modification. Level 3.3V, 5V microcontrollers must perform level conversion.
2. **Analog VO Output**: 0-3V proportional to 0-10ppm; Analog output accuracy is weaker than the serial port, suitable for simple collection.
Application Scenarios
- Monitoring of HF leakage in chemical and semiconductor etching processes
- Detection of toxic HF gas in metallurgy, electroplating, and acid washing workshops
- Fixed transmitters and portable detectors in waste gas treatment and hazardous chemical factories
- PLC, industrial control equipment, and secondary development integration for gas alarms
