The Dragino LDDS75 Ultrasonic Distance Sensor measures the distance to flat objects — for liquid level, parking bay, trash-bin fill, and proximity applications — using ultrasonic sensing with internal temperature compensation. It uplinks distance readings periodically over LoRaWAN from a rugged IP66 enclosure.
