Distance testing
1： Test environment
The testing distance is 1000M on open ground or by the sea.
2： Test environment
On a road with a small number of cars, trees, and lamp posts, the test distance was halved to 500 meters
The straight-line test distance between various high-rise buildings on the ground floor is 250 meters when folded in half. Indoors, it can cover a building with a small number of blind spots and cannot pass through steel reinforced floors
As shown in the above figure, the HC-12 module is used to replace the physical connection on the left side of the half duplex communication to send serial data to the module. After the RXD port of the left module receives the serial data, it automatically sends the data to the air in the form of radio waves. The module on the right can automatically receive and restore the serial data sent by the device on the left from TXD. It's the same from right to left
