وصف
The module is used for ultra-long-range spread spectrum communication, and its RF chip SX1278 mainly uses LoRa remote modem for ultra-long-range spread spectrum communication, which has strong anti-interference and can minimize current consumption. With the help of SEMTECH LoRa patented modulation technology, SX1278 has a high sensitivity exceeding-148dBm, a power output of 20dBm, a long transmission distance and high reliability. At the same time, compared with traditional modulation technology, LoRaModulation technology also has obvious advantages in anti-blocking and selection, which solves the problem that traditional design schemes cannot take into account distance, anti-interference and power consumption at the same time.
Applications are used for automatic meter reading, home building automation, security systems, and remote irrigation systems.
