VL53L1X ToF 레이저 거리 측정 센서 -최대 400cm
(VL53L1X Time-of-Flight Distance Sensor Carrier
with Voltage Regulator, 400cm Max)
개요
- 본 제품은 최대 4미터까지 측정이 가능한 VL53L1X 레이저 거리 측정 센서입니다.
- 레이저 펄스의 Time of Flight 을 계산하여 타켓의 컬러, 모양, 재질 및 조명 상황과 관계 없이 정교한 거리를 측정합니다.
- ROI(programmable region of interest)를 지원하여 full view field를 줄여 주거나 여러 존으로 나누어 줄 수 있습니다.
- 거리 측정은 I2C 인터페이스로 읽을 수 있습니다.
- 2.8V 리니어 레귤레이터를 보드상에 장착하고 레벨 쉬프터를 가지고 있어 2.6V-5.5V 시스템과 사용이 가능합니다.
특징
- Dimensions: 0.5″ × 0.7″ × 0.085″ (13 mm × 18 mm × 2 mm)
- Weight without header pins: 0.5 g (0.02 oz)
- Operating voltage: 2.6 V to 5.5 V
- Supply current: ~15 mA (typical average during active ranging at max sampling rate)
- Varies with configuration, target, and environment; peak current can reach 40 mA
- Fast and accurate ranging with three distance mode options:
- Short: up to ~130 cm, 50 Hz max sampling rate; this mode is the most immune to interference from ambient light
- Medium: up to ~300 cm in the dark, 30 Hz max sampling rate
- Long: up to 400 cm in the dark, 30 Hz max sampling rate
- Minimum range: 4 cm (objects under this range are detected, but measurements are not accurate)
- Emitter: 940 nm invisible Class 1 VCSEL (vertical cavity surface-emitting laser) – eye-safe
- Detector: 16×16 SPAD (single photon avalanche diode) receiving array with integrated lens
- Typical full field of view (FoV): 27°
- Programmable region of interest (ROI) size on the receiving array, allowing the sensor FoV to be reduced
- Programmable ROI position on the receiving array, allowing multizone operation control from the host
- Configurable detection interrupt thresholds for implementing autonomous low-power presence detection:
- target closer than threshold
- target farther than threshold
- target within distance window
- target outside of distance window
- no target
- Output format (I²C): 16-bit distance reading (in millimeters)
