VL53L1CBV0FY/1 - Long Range Time-of-Flight Sensor | STMicroelectronics
MPN: VL53L1CBV0FY/1 ✓ Hoạt độngVL53L1CBV0FY/1 Tóm tắt
A Time-of-Flight (ToF) sensor measures distance by emitting a light signal and calculating the time it takes for the light to reflect back from an object. This technology is distinct from infrared (IR) proximity sensors, which only detect presence, and from ultrasonic sensors, which use sound waves. ToF sensors are part of the broader category of optical sensors and are widely used in robotics, consumer electronics, and industrial automation for precise distance measurement.
Key features of the VL53L1CBV0FY/1 include a long ranging distance of up to 4 meters, a fast ranging frequency of up to 50 Hz, and a field of view (FOV) of 27 degrees. The sensor is housed in an optical module package, which integrates the emitter, receiver, and optics in a single component. It operates over a temperature range of -30°C to +85°C, ensuring reliable performance in various environments.
The VL53L1CBV0FY/1 uses STMicroelectronics' patented ToF technology, which employs single-photon avalanche diodes (SPADs) to detect reflected light. This architecture enables high accuracy and immunity to ambient light, making it suitable for outdoor applications. The sensor also features a programmable region of interest (ROI), allowing users to optimize the field of view for specific applications.
Typical applications include smartphone proximity detection, robotics obstacle avoidance, drone landing assistance, and industrial safety systems. The sensor's long range and fast ranging frequency make it ideal for applications requiring real-time distance measurement, such as autonomous navigation and collision avoidance.
When designing with the VL53L1CBV0FY/1, it is important to consider the optical interface. The sensor requires a clear line of sight to the target, and the cover glass or window must be transparent to infrared light. Additionally, proper power supply decoupling and PCB layout are critical to minimize noise and ensure accurate measurements.

Ghi chú thiết kế
Ensure the optical module has a clear line of sight to the target. The cover glass or window must be transparent to infrared light (typically >90% transmittance at 940nm). Avoid placing components that could obstruct the optical path.
Decouple the AVDD pin with a 1uF ceramic capacitor placed as close as possible to the pin. A 0.1uF capacitor in parallel is recommended for high-frequency noise. The supply should be clean and stable to ensure accurate ranging.
Keep the I2C lines (SDA, SCL) short and add pull-up resistors (typically 4.7kΩ) to the supply voltage. Avoid routing high-speed signals near the sensor to prevent interference. The XSHUT pin can be used to power down the sensor when not in use to save power.
