HC-12 wireless serial port communication module is a new-generation multichannel embeddedwireless data transmission module. Its wireless working frequency band is 433.4-473.0MHz,multiple channels can be set, with the stepping of 400 KHz, and there are totally 100 channels.The maximum transmitting power of module is 100mW (20dBm), the receiving sensitivity is-117dBm at baud rate of 5,000bps in the air, and the communication distance is 1,000m in openspace.
The module is encapsulated with stamp hole, can adopt patch welding, and its dimension is27.8mm×14.4mm×4mm (including antenna cap, excluding spring antenna), so it is veryconvenient for customers to go into application system. There is a PCB antenna pedestal ANT1on the module, and user can use external antenna of 433M frequency band through coaxialcable; there is also an antenna solder eye ANT2 in the module, and it is convenient for user toweld spring antenna. User could select one of these antennas according to use requirements.There is MCU inside the module, and user don't need to program the module separately, and alltransparent transmission mode is only responsible for receiving and sending serial port data,so it is convenient to use. The module adopts multiple serial port transparent transmissionmodes, and user could select them by AT command according to use requirements. Theaverage working current of three modes FU1, FU2 and FU3 in idle state is 80μa, 3.6mA an 16mArespectively, and the maximum working current is 100mA (in transmitting state).
