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. Key specifications Ultrasonic range 280–7500 mm on flat objects; accuracy ±(1 cm + S×0.3%) Internal temperature compensation for reliable readings 4000 mAh or 8500 mAh Li-SOCl2 battery...
