Frequently Asked Questions
Q: What is a DTof Laser Ranging Sensor Module and how does it work?
A: A DTof (Direct Time-of-Flight) Laser Ranging Sensor Module measures distance by emitting a short laser pulse at 905 nm and calculating the time it takes for the pulse to reflect back from an object. This module supports ranges up to 22 m, outputs data via I2C or UART, and delivers high-accuracy results at up to 100 frames per second — making it ideal for secondary development in robotics, automation, and IoT projects.
Q: Is this DTof sensor module compatible with Arduino, Raspberry Pi, or other microcontrollers?
A: Yes. The module communicates via standard I2C and UART interfaces, which are natively supported by Arduino, Raspberry Pi, ESP32, STM32, and most popular development platforms. With 6 connector pins and a compact PCB form factor, integration into custom hardware projects is straightforward.
Q: How does the module perform in bright ambient light conditions?
A: This DTof module features an integrated time-correlated photon burst algorithm that provides strong ambient light immunity — up to 88% at 160 KLux at 18 m. This makes it suitable for both indoor and outdoor applications where significant ambient light may be present.
Q: What operating voltage does the DTof Laser Ranging Sensor Module require?
A: The module operates at a typical voltage of 3.3 V, with an accepted range of 3.0 V to 3.6 V. Ensure your power supply or development board provides a stable voltage within this range for optimal performance.
