  The Dragino (% style="color:blue" %)**LT-22222-L I/O Controller**(%%) is an advanced LoRaWAN device designed to provide seamless wireless long-range connectivity with various I/O options, including analog current and voltage inputs, digital inputs and outputs, and relay outputs.
  The LT-22222-L I/O Controller simplifies and enhances I/O monitoring and controlling. It is ideal for professional applications in wireless sensor networks, including irrigation systems, smart metering, smart cities, building automation, and more. These controllers are designed for easy, cost-effective deployment using LoRa wireless technology.
