Waterproof TOF distance sensor IP68 RS485 Range 5m for Raspberry Pi Arduino Waveshare
TOF MINIS is a precise laser distance sensor based on Time-of-Flight (TOF) technology, offering a measurement range from 0,02 m to 5 m. Thanks to communication via the RS485 interface, an IP68 ingress protection rating, and high resistance to ambient light (up to 100K Lux), the module is perfectly suited for harsh environmental conditions - both indoors and outdoors. It is an ideal solution for projects related to robotics, industrial automation, and IoT using platforms such as Raspberry Pi, ESP32, or Arduino.
Key features:
- Measurement range up to 5 m with a very short dead zone (from 0,02 m).
- Communication via RS485 interface (Baud rate 115200).
- IP68 protection rating – complete resistance to dust and water, dedicated to demanding environments.
- High tolerance to ambient light (up to 100K Lux).
- Very narrow field of view (FOV 1,48°) effectively reducing background interference.
- Protection and safety class 1 for the laser (LASER CLASS 1).
Construction and IP68 protection
Thanks to a sealed and independent housing, the sensor offers significantly increased device protection. It minimizes the impact of external interference, ensuring a stable working environment tailored to the requirements of industrial applications.

Applications and possibilities
The sensor is perfect for tasks involving distance measurement, obstacle avoidance for mobile robots, motion trajectory planning, detection of suspended objects, or precise level measurement of materials in tanks.
