Frequently Asked Questions
Q: Is the LIHTNE XD20 TOF laser sensor compatible with Arduino and Raspberry Pi?
A: Yes. The XD20 uses a standard I2C interface, making it fully compatible with Arduino, Raspberry Pi, STM32, ESP32, and most other popular microcontrollers and single-board computers. Simply connect SDA, SCL, VCC (5 V), and GND to get started.
Q: What is the maximum detection range of this TOF laser ranging module?
A: The XD20 can measure distances from as close as 5 cm up to a maximum of 20 meters, with 1 cm resolution. Accuracy is ±10 cm in the 0.2–1 m range and ±5% for distances between 1 and 20 m.
Q: Can this sensor be used outdoors in bright sunlight?
A: Yes. The XD20 is designed to resist ambient light interference of up to 100,000 LUX — equivalent to direct sunlight — allowing it to maintain accurate readings even outdoors. Its operating temperature range of −10°C to 60°C further supports outdoor deployment.
Q: How fast does the XD20 take distance measurements?
A: The XD20 samples at up to 100 Hz (100 measurements per second), providing real-time data suitable for fast-moving platforms such as drones and autonomous robots.
