How to Use Waveshare TOF (Time Of Flight) Laser Range Sensor (B), UART
Begin by mounting the sensor on a stable surface and wiring VCC/GND along with your choice of UART or I2C pins on your microcontroller. Load the Waveshare sample firmware or your own driver code, configure the bus speed and address (for I2C), then start polling distance data at your required interval. Ensure the target is within the 1°–2° field of view and avoid direct sunlight to maintain best accuracy.

Frequently Asked Questions
How do I select between UART and I2C interfaces?
The sensor provides dedicated TX/RX pins for UART and SDA/SCL pins for I2C. Use the onboard jumper to activate your desired bus, then match the interface settings in your firmware before initializing communication.
What is the practical accuracy at different distances?
Within 0.10 m to 2 m the sensor maintains ±2 cm accuracy. Beyond 2 m up to 15 m, expect a tolerance of ±2% of the measured distance. Resolution remains 1 mm across the full range.
Can I use this sensor outdoors under bright sunlight?
Yes—its ultra-narrow 1°–2° field of view and built-in algorithm improve resistance to ambient light. For best results, avoid pointing directly into the sun or highly reflective surfaces.
