US0210 · ULTRASONIC DIST SENSOR
Ultrasonic Distance Sensor
Rev 1.0 2026-04-20
Key Features
- Ultrasonic distance measurement: 15 mm ~ 10 m, 1 mm resolution
- Temperature-compensated speed-of-sound — built-in NTC temperature sensor
- Dual beam frequency: 25 kHz wide beam (broad coverage) or 60 kHz narrow beam (tight, directional) — software selectable
- Two variants: US0210 (2-transducer, TX+RX) and US0310 (3-transducer, TX×2+RX) — pro variant achieves higher echo reception probability at long range
- Configurable max power level (p0–p4) — limits operating range to reduce interference or power consumption
- UART serial interface — simple ASCII protocol, no driver required
- Auto-output mode: configurable interval (≥ 50 ms) or on-demand query
- Compact form factor: 45.715 × 21.27 × 10 mm
