Used for wireless calling system, burglar alarm, wireless data transmission, auto data collection system and so on.
Applied to all fixed code receivers with 1, 2, 3, 4, 6, 8, 10, 12, 15 channels

The transmitting frequency, encoding mode and timing resister should be compatible with the receiver.
It is best to use the antenna of 1/4 wavelength, for antenna has a great impact on receiving effect of the module; normally using 50Ω single core cable. For frequency 433MHz, the length of antenna is about 17cm.
The position of antenna also affects the receiving effect of the module. When installing the antenna should be extended as much as possible and be away from the shield and the place in high pressure and interference.
