1. [Proximity Switch Module] Using the high-performance module, ensuring communication ability and stability. Able to adapt to DC input voltages ranging from 5V to 35V, suitable for various food supply environments.
2. [Multi-voltage regulator design] Equipped with multiple voltage regulators to ensure stable working under different input voltages.
3. [Automatic Sensing] automatically detects when the phone is approaching, enabling touchless switch control.
4. [Direct Connection] Connect directly via the phone function without the need for additional app installation.
5. [Versatile Configuration Options] Supports parameter configuration through various methods, such as APP, Mini Program, or Serial port for flexible configurations.
6. [AT Command Programming] Reserve the UART interface, supports to modify the switch lock signal value, switch lock mode and switch duration through AT command, increase module programmability.
7. [Real Time Control] The relay turns on automatically after connecting via on the phone, and automatically turns off after disconnecting, achieving real-time control of the output voltage.
