The Dragino LDDS04 is a 4-channel ultrasonic distance detection sensor with LoRaWAN EU868 connectivity, designed for simultaneous non-contact measurement at up to four independent points. Each channel features an ultrasonic probe capable of measuring distances to solid or liquid surfaces, making it ideal for applications like multi-bin waste monitoring, tank level detection, smart parking, and industrial automation. With IP66 waterproof housing and ultra-low power design, it is perfect for outdoor and harsh environments.
