PRODUCT DESCRIPTON
The ERDI LASER® LRF1200A1 is a semiconductor diode 905nm Laser Rangefinder Module using pulsed TOF technology, capable of accurately measuring distances from 5 to 1200 m on building-type targets. Designed for UAV systems, surveying instruments, communication equipment, and outdoor sports applications, it provides reliable, high-precision ranging in diverse environments.
Key Advantage
- Accurate laser Ranging: 5–1200 m measurement with ±1 m to short range and ±(1+0.4%·L) m beyond 100 m, ≥98% precision.
- Compact & Rugged: Φ23×40 mm, 18 g, IP67 lens, shock 1200 g, vibration 2.5 g, –20°C to +60°C operation.
- Easy Integration & Low Power: UART (TTL_3.3V), test software, ultra-low standby power <3 mW.

1. In this mode, the device consumes minimal power. The MCU is in an off state and does not respond to any commands. 2. When a measurement is needed, pull the enable pin low to switch the device into normal working mode and automatically perform one measurement. 3. After the measurement is complete, pull the enable pin high to return the device to low-power mode, with power consumption below 3mW. |
