The LR140 series utilizes the latest Low Power Wide Area (LPWA) technology to build Modbus/RTU communication for long-distance, wide-coverage, and low power consumption wireless IoT applications. Multiple analog inputs are supported in LR140 series, such as voltage, current and one RS-485 port for Modbus RTU Device connection. One LR140 can read more than 20 register entries from different field RTU devices in predefined time scheduling. The LoRaWAN wireless distance can reach up to 3-6KM distance depending on the environment. The LR140 series offers great flexibilities in wireless IoT applications, such as environmental sensors and meters reading for Smart City Applications such as Smart Farming, Smart Environment Monitor, etc
