Summary and Contact
A Laser Rangefinder Module is an optical sensor device designed to measure the distance between itself and a target object using a laser beam. It is widely used in industrial automation, robotics, drones, security systems, and precision surveying. These modules combine compact design, fast response times, and high accuracy, often reaching millimeter-level precision over distances from centimeters to several hundred meters.
The module's advantages include:
Compact and lightweight design suitable for embedded systems.
High measurement accuracy with low power consumption.
Wide application range: robotics, drones, industrial automation, security, and construction.
Key Features at a Glance:
| Feature | Description |
|---|---|
| Measurement Range | 0.03m – 200m (varies by model) |
| Accuracy | ±1mm – ±10mm depending on model |
| Response Time | 0.1ms – 50ms |
| Interface | UART / I2C / PWM |
| Laser Class | Class 1 / Class 2 (Eye-safe) |
| Operating Voltage | 3.3V – 5V |
| Operating Temperature | -20°C – 60°C |
Laser Rangefinder Modules operate based on the Time-of-Flight (ToF) principle. A laser pulse is emitted toward a target, reflected back, and the time taken for the light to return is measured. This allows the module to calculate the precise distance to the object.
Step-by-Step Operation:
Emit a laser pulse toward the target.
Receive the reflected pulse with a photodetector.
Calculate the round-trip time.
Convert the time into distance using the speed of light.
Output the result through UART/I2C/PWM for further processing.
Technical Advantages:
Millimeter-level accuracy for critical applications.
Fast response suitable for real-time robotics and drone navigation.
Multiple interfaces allow integration with microcontrollers, PLCs, or embedded systems.
