Hummingbird wireless serial port transparent transmission transceiver module-LC12S and Ling TR series

1. Introduction
Note that the 5V jumper is reserved. Most serial port transparent transmission modules only need 3.3V. Connecting 5V will damage the module! ! !
The Hummingbird wireless module serial port adapter board on Taobao
supports LC12S and Ling TR, and can transmit 100m and 1km via serial port.
See the previous farmland environment data wireless collection irrigation self-discipline system:

. The two combinations can be made into a one-receive and one-transmit serial port mutual transmission, and can be set to send multiple or receive multiple.
2. LC12S (100m) wireless communication settings
The setting method of LC12S 100m communication (2.4G) is the same as that of Ling TR 1000m communication (433Mhz).
First, plug in the transceiver module. After the receiver is plugged in
, there will be an extra COM port in the computer device manager. Click the tool to open the port. As shown in the figure above
, I am COM10 here, so select COM10, make sure the baud rate is 9600, USB mode A, and then click the [Open Port] button above
to open. You can click [Query Settings] and [Version Reading]. The setting parameters appear below to prove that communication is possible.
Set the channel, baud rate, and network.
Set the above parameters on the right. The network ID and RF channel of the two modules need to be the same to communicate with each other. Here I will set the default settings. The baud rate should be 9600.
After selecting the parameters, click the right to generate the command word, and the command will be generated below.
Click the right [Send] to return a message, which means that the setting is successful, and then you can unplug the receiving board.
The above is a method to configure one, and both the receiving and sending modules need to be configured.

You can see the actual measured distance in the farmland environmental data wireless collection irrigation self-discipline system project. LC12S is only 50 meters, and LingTR's 433 can reach 1000 meters

2.4G is more affected by environmental interference than 433. The actual measurement shows that the effect of 433 is much better than that of 2.4G
