This sensor is a time-of-flight laser sensor with an embedded MCU and a ranging algorithm. With a measuring range of up to 25m or 50m (Choose which version you want before adding to your cart) and an accuracy of 3cm, this sensor is ideal for projects that require high precision over long distances. It supports both UART and I2C communication, making it easy to connect with platforms such asRaspberry Pi, Arduino, and ESP32.

For wiring and example scripts for Raspberry Pi, please check this section of the Wiki.

It is designed to work in different environments, both indoors and outdoors, thanks to its ultra-narrow field of view (1 – 2) and ambient light tolerance of up to 100K LUX. It can withstand high levels of light interference, making it a great choice for outdoor use or areas with strong lighting. With a fast refresh rate of 100Hz, it provides real-time distance measurements, and its short blind zone of just 5cm allows it to measure close-range objects effectively.

Whether you’re building a robotic navigation system, creating interactive installations, or developing proximity sensors, the TOF Laser Range Sensor combines accuracy and range, making it an ideal component for any project that requires distance measurement.

Note: Please select which version you want before adding to your cart! The 25m version will have a (C) on it and the 50m version will have a (D) on it.
