[Easy to Use] HC-12 Wireless Transceiver Data Transmission Module 433MHz Wireless to Serial (แถมเสาอากาศ) - PCB น้ำเงิน

1: Power supply voltage is 3.2V~5.5V. ( If the module to work long emission state state series is recommended when the supply voltage exceeds 4.5V a 1N4007 diode, to avoid heating module built LDO )

2 : The default communication distance (open test): about 600m (the communication distance can be adjusted up to 1000m, and the air baud rate is 5000bps).

3: Default idle current: 16mA (the working current of the module is different in different working modes).

4: Module size: 27.8mm×14.4mm×4mm.

5: working frequency rate range around ( 433.4-473.0MHz , up to 100 communication frequency channel) Maximum 100mW made emission power (can be disposed opposite)

6: The module supports software upgrades. (We provide customers with upgraded software)

7: Default factory settings: working mode FU3, baud rate 9600bps, communication channel CH001 (433.4M).

Distance test

Test environment 1: The test distance is 1000M in the wilderness or on the seashore.

Test environment 2: On a road with a few cars, trees and lamp posts, the test distance is 500 meters

The straight-line test distance on the ground of the first floor among various high-rise buildings is further halved to 250 meters, while indoors, it can cover a building with a small amount of dead corners and cannot wear reinforced floors.

As figures illustrated, the HC-12 is molded block used in place of half-duplex communication when physically connecting the left side of the device to the mold block hair transmitting serial data, the left side mold blocks of the RXD port after serial data is received, from moving the data in a non- radio mode wave is sent to the air. The right side of the module blocks can be self movable received, and from the TXD further primary initial left -side devices are sent serial data. From right to left is a kind of.
