Benewake TF02-Pro-W Self-Cleaning LiDAR Level Sensor (Range: 0.1-25m) - IP5X, UART/I2C, 1.2m Cable

The integrated automatic wiper periodically cleans the sensor's front lens to remove dust, debris, or condensation. This is critical for maintaining the original ±6 cm accuracy and reliable 25m range in industrial environments like grain silos or coal bunkers where lens fouling is common, ensuring long-term operation without manual maintenance.

The TF02-Pro-W supports two digital communication protocols: UART (TTL serial) and I2C. You select the desired mode via configuration. The UART interface is common for PLCs and microcontrollers like Arduino, while I2C is useful for multi-sensor setups on Raspberry Pi or ESP32. The default baud rate and address are detailed in the datasheet.

Accuracy is specified as ±6 cm within the 0.1 to 6-meter range. Beyond 6m up to the maximum 25m, accuracy may vary slightly. The 1 cm distance resolution means the sensor reports distance changes in 1 cm increments. Accuracy can be affected by target reflectivity and extreme ambient conditions, though the sensor is rated for 100 Klux light immunity.

It requires a stable 5V DC power supply. Under normal operation, average current draw is ≤400 mA (≤2W), but during peak activity, such as when the wiper motor activates, current can reach up to 1A. Ensure your power source can provide this peak current to avoid communication drops or sensor resets.

With an IP5X rating, it is protected against dust ingress but is not waterproof. It is suitable for outdoor use in sheltered or enclosure-mounted applications where direct rain or water jets are avoided. The operating temperature range of -20°C to 60°C allows it to function in most climatic conditions, though the lens wiper also helps with light moisture or frost.
