Talk about the characteristics of radio frequency sensors

　　1. Induction distance range: 1-2000px, can be adjusted according to needs;

　　2. Small induction blind zone;

　　3. Integrate transmission and reception in one;

　　4. Built-in microprocessor, with power-down memory function;

　　5. Easy to operate, the maximum sensing distance can be set by pressing the button;

　　6. It can output level signal (high level 3.3V, low level 0V) or PWM signal, and can output distance sensing reference count value through serial port. Built-in microprocessor can communicate with other upper computers. The user can receive the distance sensing reference count value from the serial port;

　　7. Less interference from visible light and high accuracy;

　　8. Fast response speed, non-contact induction;

　　9. Cost-effective, easy to assemble, easy to use, etc.
