Product details
Product overview
Yifan Cloud Technology LoRa series module (LR100) is designed and developed by Yifan Cloud Technology. The module is used for ultra-long range spread spectrum communication. Its RF chip SX1278 uses LoRa™ remote modem for ultra-long range spread spectrum communication. It has strong anti-interference and can minimize current consumption. With SEMTECH's LoRa™ patented modulation technology, the SX1278 features high sensitivity of over -148 DBM, power output of +20dBm, long transmission distance, and high reliability. LoRa™ modulation also offers significant advantages over traditional modulation techniques in terms of anti-blocking and selection, which solves the problem of distance, interference, and power consumption in traditional designs. Applications are used in automatic meter reading, home building automation, security systems, remote irrigation systems.
