LoRa TM spread spectrum modulation frequency hopping technology, communication The distance and receiving sensitivity are far beyond the current FSK and GFSK modulation. Multiple transmission signals occupy the same channel and are not affected. It has strong anti-interference. VC1SX-1276B wireless communication series modules provide flexible channels. Various parameters such as settings, transmit power, frequency, etc. At the same time, the module has a low-power sleep function, and the sleep current is less than 2.5uA; the module supports the low-power carrier sensing protocol, and the module can automatically exit from sleep at regular intervals to listen to air data, It automatically sleeps after data transmission, which is convenient for various battery-powered systems, especially gas meters and water meters. The VC1SX-1276B-G4 module has a built-in LoraMesh protocol independently develop…
