This mini ultrasonic sensor provides UART and RS485 outputs for compact distance and level monitoring. With a 28–250cm range, ≤28cm blind zone, and ±(1+S×0.3%)cm accuracy with built‑in temperature compensation, this mini ultrasonic sensor delivers reliable performance in tight spaces. Wide 5–12V DC supply and <10mA average current suit battery‑powered devices from -15 to 60°C. Weighing just 30g, this mini ultrasonic sensor is ideal for small tanks, robotics, and space‑constrained automation.
A: Accuracy is ±(1 + S×0.3%) cm, where S is the distance in cm. For example, at 100 cm it’s ±1.3 cm; at 250 cm it’s ±1.75 cm. Built‑in temperature compensation ensures stable readings across varying conditions.
A: Three choices – UART Auto Output (continuous streaming), UART Controlled Output (on‑demand reading), and RS485 Output (industrial bus). You can select the one that best fits your host system.
A: While specific response time isn't listed, the UART Auto mode provides continuous updates, and the Controlled mode gives you reading on command – both are efficient for real‑time distance monitoring.
