Customer Questions & Answers

  • Question: What is the range of the HiLetgo HC-12 433Mhz Wireless Serial Port Module?

    Answer: The HiLetgo HC-12 module offers an impressive range of up to 1000 meters in open space. This extended range makes it ideal for various applications, such as remote monitoring, data transmission for IoT devices, or even wireless controls in robotics. Utilizing a low-frequency band, the HC-12 can penetrate obstacles better than other high-frequency modules, which is particularly beneficial in indoor environments where interference can be an issue.
  • Question: How does the HiLetgo HC-12 compare to Bluetooth modules?

    Answer: The most significant advantage of the HC-12 over Bluetooth modules is its long-range capability. While Bluetooth typically operates effectively within a distance of 10 meters, the HC-12 reaches up to 1000 meters. This makes the HC-12 a preferred choice for projects requiring extended connectivity without the complexity of Bluetooth pairing. It’s particularly useful for applications in agriculture, smart homes, and long-range communication systems.
  • Question: What type of antenna does the HiLetgo HC-12 come with?

    Answer: The HiLetgo HC-12 module is designed to work with an external antenna, usually a dipole antenna, which enhances its transmission capability. The antenna improves both the range and signal quality, allowing it to be used effectively in diverse environments. For optimal performance, ensure that the antenna is properly installed and positioned away from obstructions when implementing in projects such as telemetry systems or remote sensor networks.

HiLetgo Bluetooth Network Adapters 8541545730 Editorial Review

  • ubuy Zambia

The HC-12 is a wireless transmitter and receiver device that operates at 433MHz for serial communication. It is easy to set up and program using serial communication and has a great price. It connects directly to an Arduino and transmits straight to another unit. The device works super far; however, the communication range has not been tested. Users need to have some background knowledge in programming, but it is not very complicated. It is easy to hook up the device because it uses only two data pins. Documentation is available by searching "HC-12 code example" or "HC-12 Arduino." HC12 has excellent distance, operates in fixed (pass-thru) mode at default 9600 8N1, and works well with 1N4007 diode and a 220uF capacitor for VCC and GND pins. Its range can improve by lowering bit rates, but it cannot change powers to do so. Users cannot use HC-12 as a Bluetooth Audio receiver.
