1. What is the 4CH 27MHz RF remote module used for?
It is used for wireless control of up to four independent functions. It can be used in robotics, model projects, automation prototypes, wireless switching, remote mechanisms, and DIY electronics.
2. How many devices can be controlled with the transmitter?
The transmitter provides four independent channels, allowing four separate functions or control signals to be operated from a single remote, depending on the receiver configuration.
3. Does the receiver directly control motors or high-power loads?
The receiver output capability depends on the specific module version. For motors, high-current loads, or other power devices, a suitable relay, MOSFET, motor driver, or other interface circuit should be used rather than connecting the load directly unless the receiver is specifically rated for it.
4. What is the operating frequency of this remote system?
The system operates at 27MHz RF frequency. The actual communication range depends on the transmitter power, receiver sensitivity, antenna arrangement, obstacles, interference, and operating environment.
5. Does the transmitter require a direct line of sight?
No. Unlike infrared remote controls, RF communication does not generally require direct line of sight. However, range and reliability can be affected by walls, metal objects, electrical interference, antenna placement, and the surrounding environment.
