Its narrow beam angle minimizes cross-talk with surrounding surfaces, ensuring that measurements stay accurate even in cluttered environments. The built-in I2C bus means you need fewer wires and can daisy-chain multiple sensors on the same bus — saving time and GPIO pins on your microcontroller.\u003c\/p\u003e\n\n\u003cp\u003eFor more information on laser safety classifications and standards, visit the FDA Laser Products \u0026amp; Instruments guidance page.\u003c\/p\u003e\n\n\u003cp\u003eLearn more: \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Proximity_sensor\" target=\"_blank\" rel=\"noopener\"\u003eProximity sensor\u003c\/a\u003e\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eQ: Is the LIHTNE XD20 TOF laser sensor compatible with Arduino and Raspberry Pi?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the maximum detection range of this TOF laser ranging module?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this sensor be used outdoors in bright sunlight?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How fast does the XD20 take distance measurements?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Is the LIHTNE XD20 TOF laser sensor compatible with Arduino and Raspberry Pi?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes.
