USR IOT WH-L101-L-C

WH-L101-L-C is a low-frequency half-duplex LoRa module supporting concentrator communication protocol, operating in the 398~525MHz frequency band. Data transmission and reception via serial port lowers the barrier to wireless application development. LoRa offers the advantages of concentrated power density and strong anti-interference capability, with a communication range of up to 2500m (open line-of-sight, antenna gain 3dBi, height greater than 2m, 0.268Kbps air data rate). WH-L101-L-C adds support for USR Cloud (cloud.usr.cn), enabling data acquisition and control of customer end devices, as well as signal quality monitoring of the module itself. The module operates at 1.8~3.6V with a sleep current of only 3μA, meeting battery-powered requirements and suitable for ultra-low-power application scenarios. The module dimensions are 26.65×18.22×2.60mm with SMT packaging, satisfying space requirements for most user applications. The module offers two power consumption modes: low-power and non-low-power; and three data transmission modes: active reporting, polling wake-up, and server push. These can be configured and combined according to requirements.
