Used for wireless calling system, burglar alarm, wireless data transmission, auto data collection system and so on.
Applied with our receivers

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

Introduction of pin:

Pins Function
D0 data pin
D1 data pin
D2 data pin
D3 data pin
+9V positive power supply
GND negative power supply
ANT antenna

Firstly, connect the positive of power to the pin of +9V and negative of power to GND. In the meanwhile, connect any one data pin of D0 ~ D3 to the pin of +9V. Then it will transmit the corresponding signal.
