First, prepare tools: RF125-TX module and RF125-RA (integrated RF125-RX module, two 125K antennas, battery slices, buttons) and battery (voltage: 9~12V).
Next, the test is performed. The test location is selected on the roof of an open place, the battery connector is inserted into the RF125-TX module, and the power is turned on. Then the red light on the RF125-TX starts to flash, indicating that data is being transmitted.
①Ranging distance 6m: Put the RF125-RA 6m away from the RF125-TX module. The test position has a row of railings. The distance of each railing is measured to be 1m. The editor puts it at the position of the 6th railing and observes Does RF125-RA receive data? If the blue light of RF125-RA starts to flash, it means that the data has been successfully received.
（6m test environment: RF125 transmitting and receiving data status）
It can be seen from the figure above that after the RF125-TX module transmits data, the blue and red lights of the RF125-RA flash at the same time. The flashing blue light indicates that the data transmitted by the RF125-TX has been successfully received, and the flashing red light indicates that the RF125-RA wakes up. At the same time, it wakes up the connected device and the communication distance of 6m is tested successfully. (Note: Due to the small size of the RF125-RA, it is difficult to take pictures, so the editor put a battery next to it as a mark)
②Test distance 8m: Next, the editor moves the RF125-RA to the 8th section of the railing, which is 8m, and observes whether the RF125-RA receives data.
（8m test environment: RF125 transmitting and receiving data status）
It can be seen from the above figure that after the RF125-TX module transmits data, the blue and red lights of the RF125-RA flash at the same time, indicating that the data has been successfully received and awakened, and the communication distance of 8m has been successfully tested.
The above is the sharing of the distance test of the 125KHz wireless air wake-up and the data transceiver module RF125. Our new product RF125 module has a communication distance of 5-8m, far exceeding the same type of products. The 125K module of the same type currently on the market has a communication distance of only 4m. If you are interested in our low-power, long-distance, 125KHz wireless air wake-up and data transceiver module RF125, welcome Customers come to consult us @ firstname.lastname@example.org .
