Frequently Asked Questions
Q: What is a DTof Laser Ranging Sensor Module and how does it work?
A: A Direct Time-of-Flight (DTof) laser ranging sensor module measures distance by emitting a short laser pulse at 905 nm and calculating the time it takes for that pulse to reflect back from an object. The module's onboard processor converts this time measurement into a precise distance reading — up to 22 meters — making it ideal for robotics, obstacle detection, industrial automation, and IoT development projects.
Q: Which microcontrollers or development platforms are compatible with this DTof sensor module?
A: This DTof laser ranging sensor module supports both I2C and UART communication interfaces, making it compatible with a broad range of microcontrollers and development boards including Arduino, Raspberry Pi, ESP32, STM32, and other platforms that support these standard protocols. Its 3.3 V operating voltage aligns with most modern development boards.
Q: How does the module perform in bright ambient light conditions?
A: The module integrates a time-correlated photon burst algorithm specifically designed to counteract strong ambient light interference. It achieves up to 88% ambient light immunity at 160 KLux at 18 m range, ensuring reliable distance measurements even in challenging outdoor or brightly lit indoor environments.
Q: What is the measurement accuracy of this 22M DTof laser sensor module?
A: At distances under 6 meters, the sensor delivers an accuracy of ±3 cm. For distances beyond 6 meters and up to the maximum range of 22 meters, the accuracy is less than 1% of the measured distance, ensuring high reliability for both short-range and long-range applications.
