Laser Ranging Sensor UART (4-400cm)

This laser range sensor is engineered to detect objects efficiently within a range of 4 to 400 centimeters with a precision of ±2 centimeters, making it a versatile choice for diverse detection scenarios. Whether employed in security gate detection or integrated into access control systems, its utility extends to security alarm devices, smart trash cans, and even smart cars or robots for obstacle avoidance.

The sensor's robust metal black shell features a threaded barrel design and comes with an optical cover over the probe. This integrated design not only helps in filtering optical interference but also provides waterproof and shockproof capabilities. By using an invisible laser, the sensor is equipped to function under various environmental conditions, with an internal voltage regulator circuit ensuring consistent performance.

With three supported measurement modes, it adapts seamlessly to varying applications, enhancing its operational flexibility. The stable UART output ensures reliable communication, while the alarm output line enhances safety by triggering a steady Low output if the measurement distance falls below a preset threshold. Users should note a potential for unstable data when measuring black objects, emphasizing a consideration of operational scenarios for optimal use.
