DFRobot Laser Ranging Sensor UART (4-400cm)

• DFRobot Laser Ranging Sensor UART (4-400cm)
• Measuring Distance: 4 - 400 cm
• Comes in 3 measurement modes
• Made with metal, waterproof and shockproof
• Communication Interface: UART
• Waterproof Rating: IP67

The DFRobot Laser Ranging Sensor UART (4-400cm) detects objects in a 4 to ~400 cm distance with ±2cm accuracy. With 3 measurement modes supported, it is well applicable to various detection scenarios like security gate detection, access control systems, security alarm devices, smart trash cans, smart cars, or robots for obstacle avoidance.

The sensor metal black shell adopts a threaded barrel design and its probe comes with an optical cover. The integrated design makes the product able to effectively filter optical interference, waterproof and shockproof. The sensor uses an invisible laser and there is a voltage regulator circuit inside the module.

Featuring stable performance and UART output, the sensor has an alarm output line that will be triggered to output Low steadily when the measurement distance is smaller than the user-set threshold.
